If there's one thing I've learned from this forum, it's that it takes an enormous amount of time and effort to convince someone of "X" when they are entrenched in their belief in "Y", no matter how logical or reasonable "X" is or how wackadoodle "Y" is..
I'm not saying it's pointless, or it can't be done - it can be.
But you can't do it with 100 or 200 word posts on an internet forum, and you can't do it in 4 minutes on Zoom.
Unless you have the will and the opportunity to engage over a long period of time, best course is just to "save your ammunition" for cases where you might be able to reason effectively with someone.
So I say just ignore it.
