IndexIntroductionArgumentConclusionsBibliographyIntroductionIn Mexico City in 2010, it was “approved to allow same-sex marriage and since then, some states have continued with reforms to law” (Milenio), modifying their civil codes to allow equal marriages. However, currently there are only “sixteen states that have approved equal marriage and they have not yet been recognized at the federal level” (Forbes). In addition to the few states that have approved equal marriage, there are fewer that allow same-sex couples to adopt a child. For example, in Mexico City in 2010, reforms allowing the adoption of children by same-sex couples were declared constitutional; but it was also asked that "tolerance and public respect be promoted, since they are the basis of a secular state" (Siller). This is because there are still myths about raising children by gay couples. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay In many states the progress in this initiative has been complicated, since many argue that "the best interests of the child are an obstacle" for him to be adopted because there would be rejection and social discrimination” (Basilio); that is, in addition to the presumed scientific arguments, the prejudices still existing in society have had an influence, according to which a family is "one composed of a father, a mother and children, therefore it is not conceivable that there are two fathers or two mothers who raise a child ” (Basilio). Therefore, the analysis of adoption by gay couples and the ways in which children are raised, based mainly on reliable scientific studies, is of fundamental importance. Informing Mexican society and subsequently obtaining the legalization of adoption at a national level will allow us to institutionalize the idea that adoption itself is for the benefit of the child, regardless of whether the parents form a homosexual couple, thus diluting the prejudices that still persist . .ArgumentationWe will begin by underlining that adoption laws must at all times be guided by the best interests of the child, in the Convention on the Rights of the Child it is established that "States that recognize or permit the adoption system shall ensure that the best interests of the child are the most important consideration” (UNICEF); and the Declaration of the Rights of the Child states that “the best interests of the child shall be the guiding principle of those responsible for his or her education and guidance” (UN). We can therefore say that the authorities and also society have the obligation to guarantee children the best possible adoption and thereby allow them to improve their quality of life. The study of homoparenting is not new, it emerged in 1970 in the United States, due to "the social and media visibility that causes the increase in cases of custody disputes in the divorce process" (Dominguez de la Rosa). Despite this, until June 2018, the WHO published its classification of diseases in which it eliminated “the inconsistency of gender or trans sexuality in the classification of mental disorders, leaving it in the category of sexual dysfunctions” (Sepúlveda); that is, homosexuality went from being considered a psychological disorder to being defined as a physical problem. However, it is currently argued that it is better for a child to be adopted by heterosexual couples due to the possibility of physical or psychological harm to the child. during parenting. Contrary to the above, there are several scientific studies that support the adoption and education ofchildren by homosexual couples. Some of these studies have analyzed the effect of different parenting models on the education of adopted children. For example, in 2004, the American Psychological Association issued two resolutions and a scientific study on the topic: Resolution on SexualityOrientation and Marriage: It is stated through experimental studies that “it is unfair and discriminatory to deny same-sex couples access to civil marriage, their rights, benefits and privileges” (American Psychological Association). Resolution on sexual orientation, parents and children: This recognizes that “there is no scientific evidence to conclude that the sexual orientation of the father or mother compromises his or her work as a father or mother” (American Psychological Association); therefore, homosexual parents are just as capable as heterosexual parents of providing the adopted child with a healthy and favorable developmental environment. Lesbian and gay parenting: study that contradicts the belief that homosexuality is a symptom associated with a disease (pathology), the preconceived opinion that lesbian women are less maternal than heterosexual women and “the idea that sexual relations gay couples leave little time for fathers or mothers to raise children” (American Psychological Association). From the above it can be stated that not a few reliable psychiatric and psychological studies show that children raised by a gay couple will not be affected in their health or development, compared to those raised by heterosexual couples. ; In fact, there is no serious experimental research today that proves otherwise. In our country, several studies published by UNAM 'exclude the negative impact on the development of children adopted by homosexual couples' and also state that 'children's rights are not violated and guarantee equal access to same-parent families' (Cancino) . On the other hand, research that tries to 'demonstrate' psychological damage to children adopted by homosexual couples has several disadvantages in terms of the reliability of the results: It is a recent phenomenon and therefore the cases of analysis are scarce. For example, in Mexico City in 2018, "only 17 homoparental adoptions were registered." They present ambiguous hypotheses, analyze premeditated cases and these are too particular to validate the supposed negative or positive consequences. It is then the quality of parents' education that will determine the psychological and social development of children, not their sexual orientation or gender. In this sense, we can also state that the restriction of adoption exclusively to heterosexual couples lacks an objective and reasonable motivation, as well as constituting a discriminatory act, since their speech is based (as already mentioned above) on a physical and psychological harm to the child. It is necessary to remember that the legal recognition of same-parent families for adoption will allow the children of same-sex couples to obtain legal certainty and will contribute to gradually eliminating the prejudices that to this day persist in Mexican society and are frequently reproduced at the state level (in conferences, by public officials, etc.). The above will have a positive impact at different levels: in society, in the LGBT community, in parents, but above all it will contribute to the well-being of the child, which should be the main goal. Conclusions We can conclude that homosexuality is not a psychological or psychiatric disorder, but a variant of sexual preference. It has been proven that most homosexual people lead healthy and productive lives, as do their relationships. Thus, hypotheses that heterosexual couples will be better fathers than same-sex couples and that children.” 20 11 1989. 23 10 2019.
