My criticism of Trump is that he failed to forcefully shun people who are clearly full of hate. He winked, and gave them a place at his table.

I won't totally disagree with you. The idea that Trump, who was the most pro-Israel President in who knows how long, hates the Jews is silly -- but there are definitely supporters of his on the right who think otherwise and grew bolder during his presidency.

However, we've seen the exact same thing on the left. Biden issued an excellent statement on anti-Semitic violence, condemning it with no ifs, ands, or buts. But too many politicians and public figures on the left have either let the issue slide or all-lives-mattered it or, even worse, embraced the crazy blood libels boiling out of the Middle East, and we've seen the results in the views of younger people on the left, and in the violence committed against Jews across the country by people who are clearly not in Trump's camp.

You're probably right, though, that it's just some dipshit teenage edgelords. That's the group you can always count on.
