Sadly, even if you were to somehow avoid all the crazy videos (of which there are a fuck ton more than regular content), the comment sections are nearly always filled with literal nazi wannabies and people being openly bigotted in every possible way. Videos completely unrelated like Veritasium videos always somehow find the comments leaning into how Group X is to blame for everything and other vile stuff.
Even their own announcement posts have people being openly antisemitic as their top comments.
I'd argue its proof a little moderation is actually needed for a site not to become a cesspool.
