Mm. But notice the difference in delivery of those two quotes. This one concerns itself with a straight true statement (progress is at odds with tradition). The worst you can say here is that he says conservatives "whine".
Much unlike the other one which implies that leftists are all about power as opposed to what they say they are.
If he's an example of tribalism, as you claimed earlier, then he should be aligned with a tribe. "The conservatives are fools" is a fairly unambiguous denunciation of that tribe. Regardless of whether you feel he favors one over the other, he clearly rejects both.
