The alt-right Trump supporters will believe anything and everything that comes out of Trump's pufferfish mouth. No amount of fact-checking will change that. If Trump were to say the earth was flat, Trump's supporters would immediately flatten the terrestrial globe to conform to that illusion.
As we witness right here on RJ. They just mindlessly regurgitate pro-Trump Fox News talking points, without any regard for truth, facts or logic. At least they're predictable, and all parrot the same ridiculous things. Saves them from wasting any energy on thinking for themselves.
