That isn't true, since Mushi one of the strongest players in dota2 at present; it at least not cultural and nonprofessionally because he is a commentator. I will remind that his colleague, so to speak, Toby long and persistently apologized before audience after called someone by Niger or something in this spirit. It occurs not for the first time. On his streams it isn't seldom possible to hear insults to players.
