“there is such diversity that more often than not, rude behavior and disorder is bred.”
Surely you’re not suggesting that diversity breeds rude behavior and disorder. Are you? As far as I’d be able to tell, diversity wouldn’t really be capable of breeding rude behavior and disorder unless it was combined with intolerance.
“Needless to say, I would not recommend this area to live in.”
Why, exactly, is that? You’re not saying that the illegals are connected to the crime, and the crime rate is lower there than in most places. So yes, apparently you do need to say. Why wouldn’t you recommend this area?
