he was a blatant racist

I’m not seeing it. Most those quotes were about affirmative action logically causing him to question the qualifications of blacks (because their race got them there via affirmative action). The rest are simply not racist or just bashing specific black individuals.

I’ll say this is the only one even worth discussing, as it requires a lot of nuance. The other points below aren’t good.

little kids being killed in school shootings is “worth it”

If he could, I’m sure he would say his own death was “worth it” in the context of being able to live in a country with gun rights. There are like ~1200 children killed by cars every year. Would you say that’s not worth having cars? Would you outlaw them?

ridiculed disabled people in his circles

Making a joke about blind people is insensitive, but not even half the insensitivity of the meme in this post. I won’t defend him necessarily except to say this is a pretty mild offense, especially for someone everyone is calling a fascist who deserved public execution. I’d expect something a big more dire.

said that children should witness public executions

Do you know why? And do you have a reason for being so strongly against that? I don’t have a reason. I don’t know any studies on how this affects kids, but it could very well be a good idea.
