Because you can't logic someone out of a position they didn't logic themselves into. You're not arguing with facts, you're arguing with people, and if you argue with stupid people, they'll drag you down to their level and best you with experience.

Some people don't respond to reason or facts.

I believe the common analogy is it's like playing chess with a pigeon:

You know you're smarter and do everything right, but they knock all the pieces over, shit on the board, then strut around like they won.

What does winning look like?

Cause being right doesn’t mean you know how to argue with that person. It also doesn’t mean you remember all the relevant facts that would make winning possible.

Because "right" and "good at winning debates" do not necessarily correlate.

You can try it right now, actually.
