Neo-Colonialism
During the economic crisis that is now dubbed Shock Therapy, it got so bad that sex exploitation for all genders become quite common, even to the point where children were getting involved en masse. There was extreme wealth inequality and the rich were mostly returning from exile. These people were Putin's supporters, he could not blame the bourgeoisie for the sex crimes, so he put the blame on the LGBT. Really ps like all r-ists do it not because of attraction but because of the culture of elites to dehumanize and abuse people below them.
