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.
How is that “disrespectful”? In what way is that “disrespectful”? And if someone is a big fan of Iron man hates his current last name and wants to change it to “Stark” why shouldn’t he.
How is it not? If you change your name to specifically distance yourself from someone then that is a sign that you don’t respect that person.
Maybe you really don’t respect someone and want to show it, that’s fine. It’s ok to not respect a person if you find them unworthy of respect.
There are several valid reasons to change your name, wanting to disassociate yourself from someone is completely valid. For example, Austrian composer Thomas Wanker changed his name to Wander, more for practical reasons.
I disagree with your thought path.
A person changing his name to disconnect from a family name isn’t a direct disrespect to the family name. It is an individual choosing direct respect for himself. Family is dynamic. Blood doesn’t automatically mean family.
This is similar to the arguments about respecting another person’s religious decision.
Your religious decisions can sway any decisions that you choose to make about your life. Your religious decisions will not hold away over any decisions that I make about my life.
