My mom just admitted she agrees with Hitler…

I literally am lost for words, we were talking about the news and of course Israel and Palestine came up, she told me she saw this video of someone denying the holocaust and she got mad, not because denying the holocaust is a bad thing but because the holocaust was a good thing… yes, she said it was a good thing and that they should’ve “finished the job”, I really needed to get it off my chest because I have no idea who else to tell this, I’m confused and honestly idk what to do. She’s now rambling about how Hitler was right, I tried to stop her but she won’t listen to me…
