To call the comparison absurd and to argue why is not personal.

To ascribe motive to what you consider the absurdity of the comparison (“disingenuous”) is, as dang described it, ad hominem.

The fact that I can draw this distinction without indicating any agreement or disagreement with your actual argument helps emphasize this point.

I think you could make a very interesting comment on the distinction between the red flag lists and the others without discussing the poster.
