There is no consensus within prolewiki that determines whether FRSO is a revisionist (and opportunist) organisation. We did have controversy regarding two individuals claiming to be part of FRSO in the discord but that is not reflective on the organisation.
There is only one controversy issue here, and that must be counterbalanced from the fact that FRSO has programs mentioning the mass line: https://frso.org/main-documents/some-points-on-the-mass-line/ . Unless if we could provide more evidence of its opportunism and revisionism, this controversy issue is insufficient to determine FRSO as an opportunist or revisionist organisation. As Dave stated earlier, there is more evidence to suggest that CPUSA is revisionist, unlike FRSO.
I am not defending FRSO here, I am just upholding the goal that the FRSO article (like any other article) must impartial if possible, and I believe that the article should be reworded to be a Marxist-Leninist organisation unless there is sufficient evidence to suggest otherwise.
