This has been working for years in Rugby. The next World Cup won't be segregated either [1].

It makes for a much friendlier environment. Being able to banter with the opposing supporters prevents frustration, and I'm sure is fairly self regulating.

Complete opinion, but throwing abuse at the other side is far more likely to reach fever pitch(..) when everyone around you is shouting the same way. If half of those around you are shouting back that, no, it's you that's the idiot, then it'll come to a natural head far quicker and less violently.
