It is quite normal, that there are some kinds of Profiling done everywhere. what is wrong in like minded people(with similar habits) living in a group? Otherwise there would be lot of compatability issues (like Veg-Nonveg, Nonveg-Fishsmell, nonveg-Pork??...)
just a simple question... Would you rent your house to a Chinese or somebody who would eat Pork?? (easy to preach,but when it comes to one's own property, it is natural for everybody to look for somebody who is the closest to him both habitual,behavioural)
