Isn't this the crux of infamous "ad hominem" argument: attacking the person instead of their reasoning? Even smart people sometimes make stupid arguments. And good arguments can be made by anyone. It's very difficult to be right 100% of the time. It's also quite unusual to be wrong 100% of the time. Evaluate the reasoning, not the author. Stupid argument, not stupid person. Look at what Alsup said to Boies. Still, this is easier said than done.
