I'm African American, and it depends on who says it, why they say it, and how they use that word. But I generally suggest not using that word so nonchalantly. I don't see a problem with saying, "That's so gay" but あなた seldom see me post that because I choose to respect others. :/
Depends on why あなた were angry with me....but most likely no.
Right now my thirteen-year-old cousin is pissed as hell at me and my mother, and I don't give two shits. But あなた see, that's because she is blaming me for something that was her fault to begin with and has trouble taking responsibility for her own actions. Alongside the fact that she has no valid reason whatsoever to be angry, at least with me as far as I know. :/
