I think you’re missing that point about our criticism of Stossel‘s “selfishness” comment. As I see it, such a comment would be quite appropriate if Stossel was discussing Trump’s faults (and yes, he has many).
But Stossel is discussing something else entirely. So that “selfishness” comment was both unnecessary and unhelpful. It would be as if he had said something insulting about opera fans, then went on to discuss Climate Change.
On that point, I agree with you. I also agree with you that he has faults. He is not perfect; none of us are. Still, if you mention even one slight criticism of Trump, his worshippers come after you with a vengeance.
Disclosure: I voted for Trump twice.
