Historically this kind of scapegoating is used by politicians to solidify their bases and draw attention away from their failing policies, and no doubt this is what’s happening in Russia. Counting on the natural backlash against the success of marriage equality around the world and recruiting support from conservative religious organizations, Mr. Putin has sallied forth into this battle, figuring that the only opposition he will face will come from the left, his favorite boogeyman.
Re. your query about Animal Farm. Of course I intended it primarily as a satire on the Russian revolution. But I did mean it to have a wider application in so much that I meant that that kind of revolution (violent conspiratorial revolution, led by unconsciously power-hungry people) can only lead to a change of masters. I meant the moral to be that revolutions only effect a radical improvement when the masses are alert and know how to chuck out their leaders as soon as the latter have done their job. The turning-point of the story was supposed to be when the pigs kept the milk and apples for themselves (Kronstadt).1
