That is what is known as "confirmation bias," where the person sees disagreement as proof of their original point. Her point was ill-founded, based in ignorance, and her own political bias. Also, Mrs. Harris IS a woman! Saying so is not disrespectful, but nice try with the virtue signaling!
Also, your characterization betrays your own extreme bias. You dismiss Harris as "incompetent" and lacking leadership capabilities based on nothing at all, while Trump - an unhinged serial sex offender who committed treason and is promising reprisals and fascist violence - gets a pass.
All you've done is prove the double standard. The woman (yes, WOMAN!) candidate is subjected to severe scrutiny and dislike, while the white man candidate can do or say anything at all and still get votes.
