I cannot believe the rhetoric on this thread. "backward", "them", "us" - you sound like a bunch of xenophobes.
Squat toilets are not a sign of a backward culture and they can be found all over the "backward" southern European culures and as they require no skin contact are percieved as more hygenic.
And to suggest that "we" have not made demands on other cultures is ludicrous - "we" willfully impose our victorian notions of right/wrong, good/bad wherever we go. But that's ok because "our" way is the right way.
