Ok
Lets clarify something.
The Gemora in Meseches Chullin Daf Tzaddik Beis Amud Beis right at the top of the Amud states that one of the “Zchusim” that the umos hoilam have is that they do not write marital contracts for “mishkav zochur.
Rashi explains that is even though they actually have such unions still they do not go so far as officially issue marital contracts for them.
So the Gemora first off states clearly that the lack of “Same gender marriage recognition is one of those things which provides “zchus kiyum” and the Gemora according to Rashi clearly states that even if it is being done any way it is still far worse to officially recognize it.
Now that We know the Chazal’s views on the matter I am sure we can stop saying “well they are doing it anyway”.
