I'm sorry, but your comment is misleading and spread some things that are not true at all.
The only factor on the match between Gremio and Internacional was the "gaucho pride", "we'll set an example for the rest of the country". They are nationalists and the marketing guy played well with that. Remember the chorus on their state anthem: "Serve our achievements as example for the whole Earth".
About Sao Paulo clubs, you said about Corinthians as "the worst case", which is far from the truth. Organized supporters from Palmeiras and Sao Paulo are way more violent, their fan clubes presidents were arrested several times, most of them accused by murder, even during carnival.
So please, if we want to help non brazilians to understand our reality, we got do it with facts.
