A kind of "Lest We Forget" thing that doesn't seem to be touched on . . .
and one of the main reasons I'm never calling that orange-colored fuckface "My President" (hint, lurkers: he's not your president either, and you're kidding yourself if you think he is):
He was one of the most prominent members of the Obama Citizenship Denial, or "Birther", movement. There's a run-down of all his tweets on the subject at the Salon link for further reference.
Back in the day, I referred to these people as the "President Ni**er" Group. Shoe fits.
They never saw him as an elected official or a human being; they only saw him as a color they hated looking at and blamed all of their imaginary problems on.
Much like the historically revising idiots who participate in New Deal Denialism or calling Hitler a card-carrying Lefty, this is an example of going out of one's way to discredit an individual or a political movement with gregarious falsehoods and nutbar conspiracy theories.
The whole movement was and is un-American to the core. And now, it's most prominent speaker is President.
For now.
