People are quick to call others racist, especially in the United States and England it's in fashion to see racism, sexism, etc. behind every tree. Look, it's probably not a great idea to dress up like that, but at the same time for christ's sake do people like to get mad about anything, does it make one feel better? I am sure every one of those calling Griezmann things now have been racist themselves in some sort of way in their lifetime.
Griezmann and a lot of African-French are good buddies. His best friend Pogba will defend Antoine, I am sure.
