Just so we're all on the same - very ignorant - page, are you talking race in 2012? Come on, todays French are a big mix of whatever. This mix is what is French.
I've experienced aggressive behaviour from a lot of white Australians. Should I make a judgement of the entire population based on those anecdotal experiences?
Aggression is everywhere, it has very little to do with your cultural heritage unless you're a bloody Spartan.
If you want don't want to be quiet about your racial prejudices, go find a forum for it. There should be plenty of mindless goons out there willing to discuss it with you. Try the youtube comments section.
The fact that you acknowledge that there exists a culture whose adherents are more prone to be adversarial means you accept OP's point.
