What did someone say that made you lose respect for them?

We were in the car and there was an advert (not sure what to call it) for missing children on the bus station. I lost all respect for my mum when she didn't directly say, but she basically meant "it's the child's fault that they got kidnapped". My little brother happened to be playing dumb ways to die (yes, in 2020) and she made a reference how the kid getting lost and running off on their own is basically a dumb way to die...

I mean she already lost most of my respect when she told me about her racist beliefs and I wanna say sooo much things to her but I don't wanna cause more problems than there already are.
