My chemistry, math and english teachers are all very entertaining. Just for the record.
As for double standards, I dunno. I have a lot of opinions on racism, but not neccessarily double standards regarding racism. I don't like the fact that white people are pretty much defenseless against black people. Not that I don't like black people, but if he makes fun of me for my race, I could take it to court. And I'd lose. If I made fun of him for his race, he'd take it to court, and most likely win. Racism is all very confusing.
