> a serious intellectual is one that poses falsifiable arguments that other intellectuals attempt, and fail, to falsify. PG does no such thing.
Not really, a serious intellectual is one that does their research and does it competently, and from that foundation skillfully tries to articulate the truth. It's not a requirement that they do that within a Popper-approved framework.
a serious intellectual, when confronted with evidence that their arguments are wrong, does not simply label their critics as "haters" at every turn as PG does. The notion that someone engage criticism of their viewpoints in earnest is not restricted to the sciences and does not require specific formalities.
