"You and everyone like you should be rounded up and executed" is a just a mean message, but it's also dangerous. People will believe that stuff, and then try to do it. This isn't a theoretical danger, it has happened time and time again throughout history. These sorts of seductive messages that target out-groups and provide a sense of community have lead to real life horrors.
X has also gotten very bad about amplifying misinformation, especially on white supremacist topics. Just yesterday (maybe the day before?) that bullshit old paper that said sub-Saharan Africans had an average IQ of 55 made it to the top of the feed with no community notes. The comment section was full of great replacement theory blue check guys all agreeing with one another and making it sound like there was a consensus. People see stuff like this and actually believe it. Frankly I wouldn't be surprised if Elon himself re-Xed it at some point.
