I just found out that my boss is gay

I work for a well- known book publisher in New York City. While walking near Washington Square Park, in the Village, I happen to see my boss entering a gay bar. I know this a gay bar because I was invited to go there one night by my gay cousin and some his friends. Don't get me wrong. My cousin is a great guy. We grew up together and I love him like a brother. My cousin has been "out" for many years, and lives a very full life. So I've dealt with having gay people around me for quite a long time. But my boss - a very unpleasant, racially predjudice, fat, balding white man in his early sixties is still "in the closet" apparently. I have heard this man use the "N" word several times. I have seen him disrespecting women. I have complained to senior management about this guy more than once, and the word is that he is soon to be let go. So, would it be normal to spread the word at work about his gay side? He would not be fired for being gay, of course. But I know that it would sully his reputation even more. Once his secret is out and he learns that people at work know. He'll more than likely quit. Find another job. Or kill himself. Either one of those two choices would be find with me. Sounds callous I know. But I have good friends who have been hurt by this asshole. He's just got to go. Is my mode of revenge normal? Because of my cousin I hate using the gay thing as a weapon. But what the fuck?
