This is a question of concept. Your parents objected for your own good. Even if the other family is willing now, you will still be bullied in the future! Your boyfriend doesn't fully understand you, that's all. If you get it in the future, the consequences can be imagined, so parents don't agree.
It's not fucking insulting, it's that you want to be with such a man. . . So one is willing to fight and one is willing to suffer!
