What cross-section of humanity are you familiar with?
Familiar with? Using the most obvious definition I'd say only my girlfriend.
Due to where I live I have neighbours from a wide variety of races and religions and mostly a different class from the people I grew up with, which is different again from the class I work in now. I haven't lived for any substantial time in a different country. Does that answer your question?
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
