YTA for throwing away/damaging something that isn’t yours - your daughter bought it with her own money (and a lot of it by the sounds of it), it’s hers, NOT YOURS. What would happen if she destroyed something expensive that you cared about? Also I doubt you’re planning on giving all of her money back to her after this shitty move? Leave her shit alone.
This sounds like a hobby/talent of hers. She could make a career out of this, and clearly enjoys it. For you, her PARENT, to get in the way of that and destroy this for her is horrible. Being supportive wouldn’t kill you. YTA.
You’re really blaming your underage daughter for ADULT MEN creeping on her? YTA. Big time. You do realise that no matter what she looked like, how old she is, how much makeup/clothes she’s wearing, men are still going to do this? Blaming your minor daughter for the actions of perverts is downright disgusting, I can’t believe you think that’s okay. I hope you haven’t instilled this belief into her. Makeup has nothing to do with this.
All teenagers go through a phase of being insecure. Taking away the thing that makes your daughter feel pretty would be so damaging. You should be trying to teach her she’s beautiful no matter what, not destroying her hobbies and tearing her down. Let the phase ride out - she’s finding out who she is, what she likes, what works for her just like everyone has to. Leave her to it, it’s harmless.
But yeah, go for it if you’d like to damage your daughters relationship with and respect for you as well as a potential career.
Oh, and by the way, YTA.
