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.


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.
