I don't know if you are being sarcastic or not, but I will talk about any topic at any time, and usually all it takes is a passable free meal and a Manhattan or two (after the talk, not before!).
I learned not to use that word in public at a relatively young age. Moralistically, through parents, teachers, etc. Practically, by almost getting my ass kicked in a public bathroom at the skating rink of my local Boys' Club when I was in middle school. It was free skate, and my friend at the time and I were on the ice against the fence (no plexiglass board at the time). Two african american kids that I knew from school were walking by the rink when they abruptly stopped and one said something along the lines of "did you f'in hear that?" a few minutes later my friend and I were in the bathroom and the two kids walk in and grab us and jack my friend up against the wall, accusing him of using the n-word. He denied it, and I didn't hear it said, so I denied it too. In part because I knew the kids and had nothing but positive interactions with them, we were spared a beating. It was the first time I saw in person the anger that word could cause, and combining that with a fear of being the recipient of that anger, the power of that word hit home (at the time, I was more afraid than anything, but I distinctly remember thinking about the power of the word). It turns out that my friend grew up to be a skinhead who would have no qualms using that word to instigate, and he had some of those tendencies at the time, unbeknownst to me and probably did say it after all.
