I've just noticed something about his name, "Nikita Shavalin". He's Russian. So that likely means that he's not trolling, but telling the truth. I don't know how much you people know about Russia. But Russians tend to hate: people of color, people of different sexual orientations and people from different nationalities.
I kid you not, yesterday and a few days ago I saw something rather shocking on the television. First one was an intellectual political debate regarding the situation in Crimea. And there was this person saying, that "Westerners are trying to undermine Russian values because they are buttfucking heathens(the crowd reacted with a round of applause, mind you), and they want Russia to sink on that level". The other one was on a documentary, about a Russian Muslim who actively sought out LGBT activists and ridiculed them over the internet, sometimes even calling their workplace so they would get fired for their views.One of his victims was a school teacher who lost her job, and is now constantly ridiculed. And mind you, the documentary portrayed that guy as a hero.
So you shouldn't really be surprised about people acting up like that.
