Yes, because "ideas rooted in fascism or bigotry" is a vague phrase lacking any clear definition, and risks becoming a cudgel for cliques to use to shut down anyone who disagrees with them.

Slippery slope fallacy, however I agree the wording is too vague and needs to be more specified. Facism / bigotry are catch-all terms for a broad range of things, and the RFC should link to or include the definitions they consider, with a caveat that they may be updated at a later time.
