As a lesbian trans person I like the words dyke and tranny, but only use it for myself. They're funny and cute. I was honestly surprised to learn that people are so deeply against the words.
I agree, I was disappointed when I found out that the tr word is a slur, but that's just how it goes, you can't control people's perspective on words. The best that we can do is avoid them.
Yeah that's right, I just use it with my friends now. Before I figured out that it was such a big deal to people I actually was considering using it for my website!
