Pavel.
can you, please, explain me how one can show support for his country by insulting other nationalities?
Pavel, he may I didn't read the whole things from beginning and he may use the wrong words to describe something, BUT read what I have said about TEAM and how you should play in YOUR team
I would think that you should say to him - Sergey, I am sorry, I got carried away and excuse me".
hell no!
You are very wrong about it and should reconsider.
