If a quote on policy would be equally at home heading a libertarian or a socialist or an anarcho-primitivist blog, does it really constrain our anticipations about policy to any meaningful extent?

I read it as cautioning us to resist the temptation to unquestioningly accept nice sounding policy as good policy.

Also any quotes that couldn't be read as potentially applicable by a large swath of the political spectrum might trigger blue-green tribalism feelings and kind of defeat the spirit of the no mind killer rule.
