It's not really hatred, just prejudice. The kind of things Foofie mentioned.
Pre-judging? What about the American right to pursue happiness, according to the Declaration of Independence. If another makes one uncomfortable, why make judgements, if they are not appropriate in the venue referred to (i.e., one who uses the WASP American culture as a role model)? Remember I do not need brownie points for Heaven or less time in Purgatory (having just seen a two hour docu-drama about Martin Luther and his railing against the selling of Indulgences).
In my opinion, you are presupposing that the values you were inculcated in are a priori correct. No one has to love me. They just have to let me live in peace. And, I can be sure that values that I have are denigrated by others raised in a more "universal" orientation (such as my being comfortable with highly competitive students for high marks, and amongst some such "striving" is considered a negative quality implying some desire for superiority).
