That's an America-centric view. If you infract "Brazil is a jungle" comments, you must start infracting "Fuck Milan and Barbara Berlusconi in the ass" comments, because they are seen as trolling by the minority of members here.
So far only the Brazilian member and the bunch of Americans are being sensitive when I criticize the World Cup. I will, of course, continue doing it, the same way I'll criticize Qatar in 8 years, and you won't mind it then. Feel free to show weakness and use mod powers when someone says Fuck Liverpool or Brazil is a jungle.
