I don't see a contradiction in your example. I think such individuals are consistently being aggressively conformist with their group, but for the hyper-political, their group isn't the nation, but the party.
That seems to fit with PG's claim that "The call of the aggressively conventional-minded is 'Crush <outgroup>!'". Naturally that would extend to disobeying the rules of the outgroup, perhaps solely because the outgroup proposed them.
OK - I didn't spend that much time constructing my caricature but I still feel my point is valid if you want to modify them somewhat.
I myself remember feeling the strong pull of both "types" and I'd struggle to define myself clearly as either. (although I suspect I'm more frequently conformist than my overly flattering self-image depicts)
Isnt PG claiming that the "rules" are to value free expression and not turn people into heretics and that those who "break" this rule are bad and unworthy and never able to have new, original ideas and thus should never be listened to?
Sounds like he is trying to say "Crush <outgroup>!" to me...
