Clammy,
racism and hatred toward any particular sector of society stems from ignorance. You probably hate the things that you have not been exposed to or have experience with. For example... you probably do not have any black, asian, latino, or any other ethnic group besides your own. Trailer Parkers.. are known to be highly uneducated, unruly, and racist. All this comes from their's, and yours, lack of a quality education and a loving upbringing.
See.. hang out with your Korean buddy a little longer and perhaps you will increase your breadth of you your knowledge.
Seriously, the comments you make that put people down for no apparent reason makes you look like a fool.
