I know it's a hard lesson to learn, but these sorts of people don't, won't, and never have cared about arguments, cause and effect, or other forms of "facts or logic". They want a functional lie that gives them moral superiority over others. That's all. If they had to accept liberalism was a giant lie, they feel they'd take a significant social status loss, so their brains work overtime to make reality conform to their delusions, and when that's not possible, suddenly they aren't into all that political stuff, or it's an exception, or the classic "it wasn't real [moral superiority justification word]".
I'm no expert but my common sense is telling me bullets fall a lot slower than they come out of the barrel of a gun. Their terminal velocity is likely fairly less dangerous.
