The post you're responding to is making the argument "Claiming that you aren't unbiased does not make you unbiased. Trying to be unbiased does not necessarily make you unbiased."

That's certainly not ad hominem at all.

No, it goes farther and very clearly says it actually mskes you more biased.

That's fair, I misparaphrased. Still, not an ad hominem because its argument appeals to studies. That could be fallacious, but it's not an ad hominem fallacy.

Not to be pedantic, but its logically invalid; no fallacy is needed.
