No. Are you offended if someone refers to you as "white"? Why is it up to your friend to tell you what color she is? If she decides she wants to be called a tree, will you then describe her as "You know, the tree"? I find African American offensive for two reasons:
- Like Larry said, our neighbor is a true African American, i.e born in Africa and currently an American citizen. To use that term for some random American who has never set foot in Africa is silly.
- It separates blacks from the rest of us. An "African" American, as opposed to a REAL American like whitey me.
Anyway, I don't get involved in PC silliness. If someone got mad at me because I referred to them as black instead of African American or whatever touchy term they've decided on, I'd ignore them.
