Far-left: PSOL now, would be TNF if he was still here. I don't really see SWE/jfern as Trots so much as extremely progressive.
Far-right: Historically Klartext, these days depends on how you define far-right. In the sense of "holds the most extreme views" it might be ExtremeRepublican. In the sense of "most likely to be a Nazi", SirWoodbury. Yellowhammer also up there.
Yellowhammer is not a a Nazi at all
!
Yeah I probably misworded that, may have worked better if I put in a new paragraph. But he is one of the most extreme posters here, which I was trying to refer to.
