Something I’ve encountered constantly online is the pedantic type who simply wants to “win” the argument at any cost, and will very much argue in bad faith and ignore (or pretend to not understand) a solid counter-argument or facts that don’t fit their narrative.
I think making a good effort at radical empathy and trying one’s best to see the other side can potentially help expose the bad faith arguments. But, there are a lot of dirty tricks out there like the Gish Gallop, etc.
