(2) You don't care if secondary or tertiary points are illogical? If they're not important, or if the logical flaws can't be fixed, why do such secondary/tertiary points continue to be included along with the central point? It makes no sense to blame Peterson's camp for this in any case. The opposition should fix their damned arguments.
(3) Can you cite an example of a logical argument presented by JP's opposition that is dismissed with "that's not an argument"? Please make sure what you cite is an actual logical/dialectical statement, and not rhetoric/sophistry... that's the typical problem with neoliberal/postmodern/progressive language.
JP's philosophy needs to be attacked on several fronts, most notably his ridiculous attempts to give religion and particularly Christianity a validity beyond mere myth and collections of historical cultural wisdom, such as it was. But the complaints you raise are absurd.
