Thanks for posting this. So, now I'm learning that I've to worry about a possible legalization of surrogacy and prostitution, too... My country is beyond messed up...

This article focus on Kirchnerism, which is understable because they are the ones in power now and very supportive of the trans lobby. But, unfortunately TRA has some support from other parties, too.

The gender identity law was approved by the House of Representatives by 117 votes against 17, in 2011. Here is a breakdown by province from the representatives who voted for (a favor) or against (en contra) the gender identity law in 2011. Among who voted for it, you can see politicians from the Kirchnerism -here listed as Frente para la Victora (FpV)-, the Unión Cívica Radical (UCR), the Coalición Cívica (CC), the PRO, the Partido Socialista (PS), and others. This list comes from a pro-TRA website, but I suppose we can trust they will list accurately who is a "good ally" and who is a "transphobe". The following year, the Senate approved the law with 55 votes and 1 abstention.

The law wasn't rejected either during the goverment of Juntos por el Cambio between 2015-2019, even thogh it would have been the perfect way to discredit the Kirchnerists. Moreover, during their administration it was decided that for the 2020 census (now delayed because of the pandemic) we will be asked for our gender identity alongside our sex, under the pretext of counting the number the transgenders.

There is also a law proposal from the opposition which aims to include a third option besides male and female in our documents. Although, it seems this was not well received among the local trans and non-bynaries because they want to be able to put whatever in their documents.

I may post something more about the gender identity law and the LGBT organizations who pushed for it, later. I just need to organize the information I found, first.
