Just do what I do, Gunny. I self identify as a black lesbian at work and mercilessly tear into any sexist, racist pig who dares challenge how I define myself. It's quite liberating and you can ask any of my co-workers that I use whatever words in an appropriate context I care to. I've become so effective with this strategy that when I was threatened with suspension for using "racist terms", a black female co-worker read the complaint and looked up at me dumbfounded and said, "But you're black!?" After filing a grievance laying out in detail how I work for the most sexually, racially, ethnically, religiously and chronologically bigoted corporation in America, the suspension was dismissed with a personal apology from the Division Manager. They haven't messed with me since even though I still refuse to pull any punches.
