But remember Kim Stanley Robinson...
In his epic Mars trilogy, many Arabs travelled to Mars and some brought their factions and fueds with them. Plenty of other people behaved badly, too, so it wasn't just them, but it illustrates the problem of colonisation.
Here in Australia we certainly observe that some groups bring their dirty laundy with - politically speaking, and the fueds live on in a new country, sometimes after the problem is resolved back home. Immigrants certainly tend to live in a sort of time warp, reliving the customs of home, at the time they left.
If we ever get to live on Mars, it would be a Generation before the colonists would feel they were Martians, rather than immigrants, imho.
