Let’s say a man decides to change his last name for no other reason than he hates his dad’s last name, and that dad refuses to call his son by his new last name. Then, in my opinion, his son should be 100% allowed to call him any mean name or slur he wants—‘dick,’ ‘shithead,’ the R slur, whatever. You shouldn’t get to disrespect people and expect respect back, so if this person gets called a slut and gets mad, I really can’t feel sympathy for him.


Not really; remember the then-little girl named “Abcde” by her parents whose case made the news after, I think, a flight attendant or gatekeeper or someone during her family’s travels was reported to have laughed at seeing her name?
I was no longer talking about OP but just in general giving a perfectly valid reason for a name change. We don’t exactly get to pick into whose families we’re born and parents certainly make suboptimal decisions from time to time (if not far more frequently)…
Oh so you’re completely ignoring the context of OP’s decision and pretending that I’m making a blanket judgement on all name changes, glad we cleared that up.
That… was my whole point of talking; when I said this:
I was already just talking in a general manner, not about this particular case. So, generally speaking, do you then actually agree?
You weren’t talking in a general manner, you invented a very specific scenario in which someone might want to change their name.
I wasn’t talking generally either: I was addressing the scenario raised by OP. Stop pretending I was saying something I wasn’t.
