It never shuts them down. It just annoys them to further irrationality.
“...It just annoys them ...”
Which is MORE than enough reason right there to do it...
“Get in their faces”, didn’t a certain douchebag say to his adoring fans, some years back???
Well...that's when the fun really starts.
Yep, their minds are made up and no facts will dissuade them, I’ve tried. Same as arguing facts regarding global climate change.
Hat tip Ron White - you can’t fix stupid
Indeed it does not shut them down...but it might make them retreat to rambling defense mode. This is that state someone gets in when they are doubting their own position but are too loathe to acknowledge it even to themselves...and they have to ramble on for a while to maintain the polite illusion of intelligence. I find it best not to embarrass them by pressing the point once they are there. Just be prepared to put them back there the next time they say something stupid...but don’t antagonize them or get riled up. This approach will persuade over time. No approach persuades over night unless you are dealing with somebody rational already...and liberalism does not manifest in such people very long. We have to train patiently....
