it quickly became apparent to me that the writings of prominent anti-hereditarians raise many more red flags of kinds that are readily apparent even to a reader without an in-depth knowledge of the subject.

That is my general impression also. But the presence of bad arguments is a very indirect indication of where the truth of the matter itself lies, so weakly related to the matter that I judge it completely worthless. It may be interesting for other reasons, but does not bear on the primary matter and has a negative effect on the whole discussion. I have not seen a convincing reply to some of the technical matters that have been raised by the anti-hereditarians; the argument is too easily derailed into attacking the anti-hereditarians' politics.

ETA: Perhaps more important is arguments being derailed into focussing on the weak points only.
