Back in the 70's, I still encountered people telling "n..." jokes, and sometimes some other people laughed. I still ran into people using that word. At that time, it took a little bit of courage to walk away from the racists. But more and more people did it, until gradually the racists were ostracized or shut up.

There are probably some of them around still, but they know it's not acceptable. Eventually, that's what will happen to homophobes. People can learn. Sometimes they're the haters, and sometimes they're the ones who can't quit arguing with the rigid haters.
