You won't change their minds, so why bother? Besides, you're unlikely to be able to engage with them without harboring (and maybe even expressing) some level of spite, which isn't good for them, for you, or for the prospect of changing their minds.

Little. But there are less idiotic people with similar concrete minds who make discussions also futile.
No but only because that requires a Ouija board.
