He's already abusing several things but I guess Russians are blind to it or just used to Putin. Someone has bombed our city, we must further restrict the rights of our citizens, bringing more violence onto the streets.
And this is where you're wrong: the majority of Russians support Putin in whatever he does and not only they're aware of his "abuse," they want him to do it, want him to continue.
Don't even go there. It's very reminiscent of what Hitler did to the Jews...
I am not sure whether Hitler had support of the majority when it comes to Holocaust; here, it's pretty clear that most hate gays and don't even consider them to be humans.
I doubt, however, that there will be concentration camps for gays in Russia. While Putin may be able to find some way to pull that off, the hatred for gays is used as a cover to pass laws which will help bring back censorship.
There are lots of peopleâ€â€most of them born in the USSRâ€â€dreaming about the return of the crumbling Soviet gerontocracy, and lots of people who just don't care about what's happening in their own country. In reality, the USSR never fell apart; it's just it's much weaker today than Russians want it to be.
Putin is pretty much the embodiment of the beliefs of an average Russian. People started worshipping him even before all the propaganda was properly launched. He is a dictator, yeah; unfortunately, people are fascinated with that.
That said, Putin doesn't actually need to use such incidents any more; he got what he wanted long ago. It's much more likely that someone sent him a message this way.
