My opinion on cross breeds.
Let me just start by saying that I am from the U.K. and our boons are not quite as savage as the ones who are running feral in America although the newer (immigrants) will be making sure that they live up to yours, especially those filthy Gambians and similar types, I work around them and you can see that they are devils, their eyes red and white and evil look they give. Vile beasts indeed!
Anyway back to my thread title, I find that the cross breeds in the U.K. always have a huge chip on their shoulders and usually more so than the pure jigaboos. They seem to look for trouble and think they are tough and cool, pseudo alpha males without a father figure full of insecurity due to the lack of father and knowing that they don't really fit in properly with humans or boons.
