Yes, brainwashing the credulous is easy. "Hey, look over there! A big bad bogeyman. Let's get him." Show a few pictures and whatnot, hey presto, the attack is on. People play rugby, boxing, soccer, as sublimated wars.
Soccer hooligans are notorious for rioting and actual fighting. When they aren't having real wars, they pretend to be having them and get seriously worked up about it. So when a real baddie is pointed out, it's easy to get on the team. The baddie is always the opposite team and their leader. Easy peasy. Just like chimps do in the jungle. Except now the opposing sides often wear pants. But the mating, eating, bullying and fighting are much the same as in the concrete jungle.
Incidentally, it's not gorilla war, it's guerilla war, but I can see how the mistake is made as they sound the same. Like tow the line, viola, could care less, and other ignorant Americanisms.
