I also think a lot of trouble that come's from within the Muslim community is first cousin marriage which can create genetic disorders which could explain the hot headed nature of some males.
Firstly, first cousin marriages cause a small increase in likelihood of congenital disorders showing theirselves as if there are recessive genes that have them then they are more likely to be able to get it from both sides, leading to it being exhibited. Same would apply for any positive genetic traits too, so if they could be congenitally predisposed to be more resistant to certain diseases. This is the less offensive comment dealt with.
As for "genetic disorder" meaning hit headed? How on earth do you draw that conclusion. Cones out of the same drawer as the idea that anyone with any sort if mental illness is a "nutjob" who should be kept away from normal people as they're probably dangerous. Frankly unbelievable prejudice.
