In a way, yes, but look around the world, wherever they are, they aren't doing much to repair that image, to put it nicely.
My experience, which has been a lot more personal than average, is that being foreign is what they seek. They expect others to conform to them, instead of adapting to the lands they migrate to.
The only ones I've encountered not like this and who actually like it here have been from Gambia, Senegal, Ivory Coast, and other African countries. Except Somalis, they might as well be from the Arabian Penninsula. And likewise, their actions reflect their attitudes. It's rather chilling.
