> What is the goal when you start arguing with someone online? Is that goal achievable?

I'm sure this is some sort of confirmation bias, I've noticed fewer stupid talking points for topics where I argue about online. I doubt it has any impact in people's political beliefs, but people end up being slightly less ideological and more hedgey. IMO, establishment figures are too dismissive about engaging with the public because they think they're above it, but this is how you end up with DOGE laying off departments only to beg for them back.

Also, honestly, I just enjoy the feeling of putting a dumb person in their place. Occasionally, I'm the dumb person, but I don't really mind that since I'm not really tied to any viewpoint. Being more informed also satisfies my mild superiority complex. Also, even if I don't learn from others, generally learn from the process of defining my arguments.
