I can honestly say i have not met many Muslim that outright disliked. I disagreed with them strongly on many topics but for the most part were cordial.
Generally the black American Muslims i have met were the worst. I am referring to the ones that follow the Nation of Islam. Most if not all of these are converts.
As for African Muslims, all the ones i have met were poor and that probably had more of an impact on their attitude then being a Muslim.
Most of the ones i deal with are well educated Indian or Pakistani Muslims, assimilated and moderate.
One thing that seems to be universal from all the Muslims i meet is they dislike Israel and Dogs.
