The Mexico City local assembly voted today to allow same-sex marriage, 39 to 20. The city had already passed a domestic partnership (leyes de convivencia) bill in 2007, but that was considered a symbolic victory at best, since it provided no more rights to same-sex couples than those already permitted under the law. This same-sex marriage law, which D.F. mayor Marcelo Ebrard is expected to sign into law, looks like a much more sweeping measure, and will allow gay couples to adopt children, be covered under health insurance plans, and to apply for bank loans as a couple.

Second, Gómez del Campo and her followers argue that adoption by same-sex couples is against the rights of children. Having total support from President Felipe Calderón, Gómez del Campo has been promoting her cause through the press. Also, in order to prove how right she is about how a family should be, she conducted a survey to ask if Mexican people agree or not with same-sex marriage. The survey proved to be tricky sooner rather than later, but sadly enough it also proved to be a tool to promote negative opinions regarding GLBT families within Mexican society. [...]
