I don't think accusations of revisionism are particularly productive at this point. Party A can accuse party B of revisionism and vice versa and who benefits? Someone accuses CPUSA of revisionism, someone else starts calling the PCUSA names, another person goes on a diatribe against the PSL, and what was gained from all of that?
I think we should focus our criticism on more specific instances of where certain individuals or parties fail and adopt erroneous positions and policies (and JT certainly deserves a lot of criticism for his latest video), while accepting that it is to everyone's benefit if we don't entirely dismiss them or label them this or that derogatory term.
Let's instead work with them on a case by case basis where our goals and strategies align.
