And this is just a personal thing, but I’ll often get more involved with arguments than with learning when my brain is spent from work. It’s easy (for me) to point out propaganda and cognitive dissonance, and yes to call people names. It takes more mental effort to learn or teach.

So you're here to play a game. To play whack-a-mole. I find that to be a disturbing approach to interacting with humans. I know I'm idealistic, but for anyone who (like me) is attempting to have real human-to-human conversation, someone coming in with the intent to just shout "fallacy!", "propaganda!", "wrong!" and play a game is extremely offensive.

For us (democrats, and US leftists in general), ignoring that fact got us Trump in 2016, and I don’t want to make that mistake again.

You have contradicted yourself here with another of your comments. In another comment you said

How often have you managed to convince someone of something by arguing with them on the internet? Or been convinced of something yourself? It’s quite rare.

And now you're saying you have a duty to convince others to change their mind by arguing with them on the internet. So is honest argumentation effective or isn't it?
