Mostly, yes a lot!
Writing about my thoughts, opinions and positions has helped me understand them even better!
You're rarely going to change anyone's position online, as sadly most aren't arguing in good faith. BUT responding to rebuttals from others and questions (good faith or bad faith) leads to a very cool intellectual exercise where you get to probe your positions from so many different angles.
If things become toxic or brain-rotty, then you can just disengage without explanation! Kinda cool actually!!!
