I think the whole anti-ɧoɱosɛҳųαƖ thing in Russia needs to be seen from the frog boiling in water perspective. We are the frog looking out.
Russia has a lot of problems with rampant alcoholism, incredibly irresponsible and dangerous driving, extreme risk taking, fatalism in the culture, and an enormous amount of pre-marital sex (even before it was a near universal feature in the western world it was problem under communism).
What it does not have and never had, is very many ɧoɱosɛҳųαƖs in the media or on TV. There has been no agenda to normalise ɧoɱosɛҳųαƖs and make them a part of everyday life, as has so OBVIOUSLY happened in our countries. I think, if there had been, Russia would have folded like anywhere else and would have ɧoɱosɛҳųαƖ marriage today.
Westerners expect and value a free press and free elections. Most Russians simply don't care. They believe that the elections will be unfree even if they are seemingly "free" so what is the difference?
Russians are VERY stubborn, proud and they don't like being looked down on as second class citizens.
I think the real reason behind the anti-ɧoɱosɛҳųαƖ thing is that it is a good line in the sand for Russian nationalists and just Russians in general to stand behind and point out the difference between their society and the west.
To them, on this point of ɧoɱosɛҳųαƖ rights and acceptance we look insane.
