Your logic is as amazing bad as ever. Nothing you said actually refuted the gullible point. Don't worry, those who voted for him aren't all being lumped together, even if "half" of them can supposedly be described as deplorable and the other "half" as gullible.

But that's what happens when you paint with a broad brush, at least that's what they tell me.
