Does it bother you when people of a certain ethnicity prefer not to date within their own race (i.e. African-American guy preferring white girls, Asian-American girl who doesn't date Asian guys, etc.)?
No, everyone has the right to choose whatever mate they please.
Do you think that the trends of minorities becoming the majority and whites becoming the minority in this country will have a positive or negative impact on race relations?
Positive, may take a minute though.
