I'm sorry but I can't put this any other way. I'm at a loss.
Why is it, that every time, EVERY TIME, you ask Russians to please stop blabbering in cyrilics in chats, that they will always insult your mother and call you a nazi? Every time. Without fail. No matter how polite you are, they refuse to take their private conversations in anything but public channels. Especially in mobas, where team communication is important.
I don't understand it. I haven't met a single polite, English speaking Russian. Not one. I'm sad to say this reflects very poorly on Russia as a country.
Hell, I've met both French and Germans who politely apologize and explain if you ask them. But Russians always spew insults and call you a nazi. No matter the subject, you're always a nazi.
