I don't mind being called anything but negative racial slurs. Black is a widely accepted term for African Americans/Americanized African descendants, and I don't have problems with it except it seems almost dumb to be called by a color that doesn't ACTUALLY describe your skin tone (as I am more of a brown than black :/ ) but it's not a big deal I guess. Equally... incorrect is calling Mexicans brown people. But, it doesn't offend me to be called black. I know humans will always seek words to classify things and group things/people.
