There are examples of both good and bad in every religion and culture; but in general, I find, everywhere that I've been, the general Arab outlook is one of hostility, angst, sexual discrimination, and ass-backwards thinking, intolerant, and unwilling to work within a global community. Wherever they go, they do not acclimate to the local laws and customs, but bring their own; I'd say one in three are fundamentalist in their system of belief, and one in two, secretly if not flat outright, do not believe in any kind of tolerance nor the morals and ideals associated with the modern world.
There is something to be said for a continent of individuals whom are completely segregated from the world, and one another, whose entire existence for the last thousand years has been marked with warfare, and with a complete failure to give rise to anything productive to the world, where the only rise has been a rise in fundamentalist religious belief, while the rest of the world moved away from that mentality.
