Just for let you know and i hope to put a end on this flame war, i think that the Majority is just a pure excuse to cover the lack of knowledge that some country have.
I mean; i come from Italy and i would never speak on a chat channel for example help one in Italian since is a game played by many countries and as far as i know at school the most important second lenguage they teach is the english so use it, is it too hard?
i am a old Tibia player and i can tell you with any doubt that in every guild i was all the player was talking in english no matter if the majority of them was Brazilias, Mexicans, Spanish, Canadian or Martian.
To finish, i can tell you in base of my experience that the two countries that hardly do this are the brazilian and the polish ones.
You may say to me, you have a bad english, ok but at least i try to be understood.
This is just an article i found on the net:
