>unapologetically racist and antisemitic.

Anyone who's actually familiar with 4chan knows that posts containing any of that are cracked on hard, both by other users (replies calling it out) and janitors (delete+ban).

Is this actually true? So they just get around it with countless dogwhistles that mean the exact same thing?

Every single page is filled to the brim with racism, that is evident to anyone who has visited the site.

Arguably that's where the current generation of dogwhistlers learned their craft.

Musk is supreme at it ("kek").

I'm not sure how you've come to that impression. The boards I used to frequent are hobbyist ones, not political, yet they have people calling each other the n-word all the time. On /fit/ anything done by a large corporation or as a moneymaking scheme is talked about as if it's a Jewish conspiracy, to the point where they call highly-processed food "goyslop". /g/ hates Indians and calls software and technology that it likes "the white man's choice." I could go on. This pervasive background of racism is all over 4chan, and I wonder why you're trying to downplay it.

I'm actually familiar with 4chan and lurked on it when I was underage at least daily. It was funny for the time.

I'm not sure where the idea comes from that the entire site's reputation is containerized inside /pol/ or any NSFW board. It's just misleading if you take 5 minutes to browse around (if you still can, anyway). The language and harassment used in ALL boards of any group of people or individual is disgusting.
