Add to that the built-in handicap because this community (like every other) values in-group opinions much more than out-group opinions, and it doesn’t make sense to even try better/longer arguments. I’m going to stop participating in controversy on this site, and move the infowar project over to audio chatrooms, where a conversation like this actually has a chance.
To everyone else: Arguing controversial topics with strangers, in Reddit-style text threads, is primitive and ineffective. The technology is insufficient for the task, and it will never get better.
