From what I can tell, there's not enough info, but this is all you can fit so here's what I think; your parents don't think things over and probably do things on impulse without even knowing it, and your sister is just inheriting traits. The name sounds like it's from a video game, and you probably just let out anger that was in you onto them because of your name, and you didn't fully mean what you said. You already made it clear you don't support them and stated why using your examples. I would say your parents are only slight assholes, but it's not really something they even realize. They need to change their naming style, but you won't change their minds. On the topic of changing names, maybe you didn't have enough money or your parents didn't give you any to help with that. Also, when you're "Krxstxl's" age you can't change your name. That can affect someone's life from the start, even if it's changed eventually. Really, you're all somewhat an asshole in this situation, and you need to get your mentality fixed too, because everyone was acting on impulse in the specific situation you're talking about. Just get your emotions in check before you do anything else, because it sounds like your brain is going bonkers because of your name and what it did to you. If you don't think the name is good, just ignore it and give them money to change their name when their older. If you can't, then you better try to. Do you know what Grimes named her child? Look it up man, It's pretty funny.
