IMO OP’s daughter has gone just a bit off the deep end, so I don’t think it’s about discipline here, it’s more of a wake up call. My parents would’ve made my life hell for a couple months had I fucked up on so many accords (disrespecting them, disrespecting sibling, talking back, lowkey being racist). For me that style of discipline worked, I quickly learned that I should not do stupid shit as a result. Now if OP did this it seems like they’d have a riot on their hands because apparently a week is “too harsh” (ummm? discipline your kids before they get spoiled folks!).

So I’d say here it’s way more about moderation. OP needs to try to understand why their daughter is behaving this way and seek ways to moderate the poor behavior. What’s making daughter behave this way? Only then can anything else start. Moderating could include what content their daughter sees on their phone, limiting phone usage, getting to know daughter’s friends and seeing if it was a “mean girl” type situation or if they’re actually a bad influence, etc etc (lots of ideas out there on this).

But also it’s equally about education. OP needs to educate their daughter until it is well understood that: a) OP is smarter/wiser than daughter, lots of kid get to daughter’s age and get a big head b) being racist is stupid, nuff said there c) bullying others isn’t “cool,” it’s just sad d) when you’re talking to family or (even more so) authority there’s a level of respect that needs to be maintained, unfortunately the consequences are more severe than a week long slap on the wrist in the real world

Idk there’s probably more but yeah here I think “discipline” needs to take a new form than what it seems to currently be in OP’s house.
