There's definitely a core group of edgelords on that site that were active on reddit during its alt right heyday, and since migrated from other dead sites like ruqqus. They can be pretty extreme, but also extremely funny and good at summarizing(and sometimes exagerating) a lot of the worst of Jewish behavior. You can usually tell the Jewish imposters by the fact they arent really funny at all. They know the lingo and the talking points, but just go for over the top shock value and fed posting. They're like a shitty off brand immitation of the alt right with the usual obvious attempts at subversion. The left really cant meme.
