What is his excuse for his bigotry once the west is defeated and the gays arent a color revolution tool of the west anymore?

He doesn’t have to come up with one. This won’t happen in his lifetime.

And you pretty much arrived at your answer to that first part - why wouldn’t he do the easy thing and turn a narrative West weaponizes into an attribute of the enemies of Russia for internal propaganda? Especially when he has to deal with a multiconfessional country, largest religions being Orthodox Christianity and Islam?
