Sounds like you inferred something that wasn't there. I said doesn't infringe on someone's rights, not "doesn't negatively impact" others. Big difference.
Also, I have not said the work Bruce since my first post, and it was in response to ...checks notes... Troph's wife posting a Tweet/X post saying Jenner voted to be called Bruce.
Since then, I have used the terms Jenner and They, so no, I haven't been blasting "polka music" ...which is Czech, by the way (meaning little Polish girl) not German. The German equivalent is Oom-pah which you noted. But I digress...
I've spent the rest of my posts differentiating between generalized slurs, IE N-word, T-word, R-word, etc, versus individualized slurs. Which somehow you put in quotes as, "Well, she's not the intended target of my insult". While it's true I am NOT, nor would I refer to Troph by her dead name (unless she too voted for Trump), I simply don't see the correlation between disrespecting an individual (Jenner) and disrespecting a group (Trans people).
I have a "dead" last name, so I might have a little more perspective than you. I was adopted by my stepdad when I was 7, but I never felt comfortable with his last name, in fact, I hated it. When I was 19, I changed it, but some people still referred to me by my previous name. Sometimes as a habit, but other times as an insult complete with the not so nice, play on words that my former last name afforded. But I never thought they were insulting all adopted kids who didn't like their adopted last names. Frankly, it didn't even bother me. It was a "them" problem, not a me problem. Just as you can, and probably do, view my opinion as a me problem. Which is fine, and your right. I simply don't care.
My responsibility in life isn't to tip toe around other people's feelings. I try to be nice to people who are nice to me, but I'm not going to bend over backwards to spare people's feelings. If that's being an asshole, the I'm an asshole and I'm fine with that. Not everyone is going to like me all the time. I agree with many on here about a lot of things, this just isn't one of them. I feel like we've become a culture of whiners who get offended too easily.
There is plenty of bad shit heading the trans community's way if certain people (people Jenner voted for) get their way. Jenner being called by a dead name shouldn't be high on that list of concerns.
There's a saying I learned in kindergarten that we might want to refer to from time to time ...sticks and stones may break my bones, but words will never hurt me.
