Are eyebrow slits bad?

I turn 15 in two months and tonight I asked my mom if I can slit my eyebrow, she said that if I mess up I still have to go to school. So I did it and I love it but my dad said that he hates it and that it’s lame. He said that I look like a Mexican drug dealer (Im not even Mexican) and that it’s embarrassing to have other adults look at me and that I ruined his night & I make him angry every time he looks at It sucks because I liked it at first but now I’m not sure if I’m wrong or not I thought it looked cute. He even tried to show me this boy band with slit eyebrows that he thought was lame but I told him he wasn’t going to change my mind and then he sent me to my room so idk if what I did was wrong or not.
