My son also has no respect for me whatsoever. He doesn’t like me, care about me, and finds me annoying. He straight up said, ‘I couldn’t give a fuck less about you or your opinion. The fact that you think I should care proves how utterly stupid you are.’ He doesn’t consider his mother’s brother or cousin his ‘family’ either, and he truly doesn’t give one fuck about what I feel about this decision.
I think the best course of action is to put your foot down and tell him he's stupid and crazy for wanting to name himself after a character he likes. Surely belittling him and trying to control his life will earn his respect.
Seriously, though, what the fuck are you thinking? Your kid is rebelling against you and your family. He wants an identity that he can be proud of, and for whatever reason he isn't proud of your family name. You don't tell us why, but your reaction to it is a strong indicator of how you treat your kid.
Have you tried being supportive? Have you tried loving your child regardless of whether he makes decisions you disagree with? Have you tried listening to his feelings and understanding his motivations without judgement? Have you live your life as an example for how to be a good person and make good decisions? In other words, be a parent. It's never too late to change.
One nation, indivisible...
Hold up, can we squeeze some division in there to make it clear we're not one nation?
