You know what? You're right. It's unfair of me to hit disagree without presenting a direct response. To be honest your last line is something I vehemently disagree with:
I think this is a bullshit, short-sighted, selfish, and stupid opinion. It shows a complete lack of empathy for a group of people who have struggled with marginalization for all of history. We've had maybe a half-decade of recognizing that maybe terms like tranny are offensive and perhaps we shouldn't make jokes where the punchline is that someone is transgender.
Wait, what? Actually, hey you're still right. I hit disagree so of course it would come off as a blanket disapproval when actually I relate to the story about your daughter and don't agree with shaming you for calling her such.
Oh... Uh, wait-
Hmm, uh, well... You- Um-
Gotta say it feels like you're taking one incident and-
Really feel you're taking this a step too far-
Maybe I'll stick to red X's.
PS: It's hilarious how transgender people deal with ridicule, attacks, and dismissiveness their entire lives as they struggle with their identity but also get criticized for worrying about their feelings too much. Meanwhile you get asked to change your pronouns or have one incident at a grocery store and it's all FUCK EM I DON'T HAVE THE PATIENCE FOR THIS I'M OUT. Unless this was satire in which case solid.
