Although I realize the rage this causes many, it made me laugh a wee-bit. In my early stages of transition I hated hearing it. In fact, I still don't like to hear it, but know it makes me laugh <internally> and realize, hey it is what it is. Hey, some can be a pretty girl, and a hot guy, you know? Or neither. Or one or the other. We're all good looking to someone so it's really all irrelevant, but it still bounces off the brain.
This situation has one OUCH to me, because of my transition, my one teacher whom I was close with in HS knows of it, is fine with it, a little "upset to see the girl of me go," but is totally accepting. And I'm accepting of the slight nasty tone that leaves. Hey, different generations have a stereotype with them, you love 'um or leave 'um, and I know she means well. But, she said to me, "I have to say though, I don't think this would sit well with Mr. W. I won't bring it up for fear on how he'd react. He always thought you were just the prettiest! He _blahblahblah_ more stuff."
It sucks! He was a bastard of a teacher, honestly. However, I had it made-- the guy used to pick on my mom back in the day, so when I rolled in he assumed I was a nightmare like she was. But I wasn't, so I had this sort of funny path to be the kid that got humorously tortured daily and it gave me something to look forward to on a daily basis. I wrote him a few times via snail mail to say what's up, but since transitioning, I know seeing him would probably not go over to well.
Then again, many people can surprise us. But with her advice on it, scared me, and saddened me. Thinking of that VERY STUPID, yet ultimately depressing insult, "WHY WOULD YOU DO THIS TO YOURSELF?"
Hm. I had no clue it was criminal to be me.
