Ask them, when you say "no evidence", do you mean that you have personally reviewed all of the evidence, and decided that none of it was credible?
or do you mean that you have literally never seen any of the evidence, and therefore you are absolutely ignorant about all of the evidence?
Because I’m pretty sure the video of an election worker pulling a box full of ballots out from under a table cloth, has never been “debunked”.
Most of us here have had to go through that. It's unpleasant, but you feel wiser on the other side, even knowing there's still a lot we don't know.
