Red Flags in Pop Fandom Opinions

I recently told someone that my number one red flag is if someone is hating on Britney Spears or Megan Thee Stallion. They've both been through so much with such grace, and at this point, if someone is still spewing negativity about them, it feels cruel and beyond unnecessary. I would leave a date over this and never return; I genuinely could not trust someone who would say mean things about either of them in public.

My friend responded that they find it to be a red flag if someone spends any amount of time commenting on a singer's weight. I agreed with that too, and it got me thinking... what are your pop music red flags? The kind of opinion that makes you instantly lose respect for someone and want to never speak to them again.
