The 4chan moderators are rarely enforcing the rules against racism, like anti-semitism, on the extreme boards, and sometimes they don't enforce those rules on non-extreme boards too. The anti-semitism on the extreme boards is rampant. It's pretty clear that the far-right is the current social phenomenon that is driving modern racism and anti-semitism, at least in the West.

That really depends on who you ask. There are many Jews who insist that left-wing antisemitism is a big problem-some will even argue it is as big a problem as (or even a bigger problem than) right-wing antisemitism. And it isn’t just right-wing Jews who speak of left-wing antisemitism as a big and growing problem - the ADL, which is very much a respected part of the American Jewish establishment, is saying the same thing - https://www.algemeiner.com/2022/09/06/adl-ceo-left-wing-anti...
Some truth in that, in Western countries right now, but less so historically or globally. Stalin re-criminalised homosexuality in 1934, and in Russia even today you can find far-left people whose views on LGBT issues are largely indistinguishable from those of the far-right. I’m sure some are going to argue those people “aren’t really left”-but unapologetic Stalinists really are far-left not far-right, and the anti-LGBT stuff is just their following in Stalin’s own footsteps. There are heaps of Western right-wingers who are far more LGBT-friendly than the average Russian Stalinist
However 4chan has always had, and continues to have quite broad demographics, it attracts extremes, by nature of it's low moderation and permissive content policies.
Some examples of left wing associated content could be it's very active LGBT user base.
It's involvement political movements like "anonymous", targeting groups like the Westboro baptist church, hacking the website of Uganda's anti-gay prime minister, occupy wall street, etc.
