This is mostly just an emotional outburst, but I’m not entirely sure that the answer is no. I don’t think I’ve ever seen any discussion about social issues in any Internet forum, where anyone seems to care about the actual reality of what’s happening in the offline world around them. It all looks like strictly a roleplaying game to me, a mockery of formal debating where each person makes their own rules and keeps their own score, but one rule everyone seems to agree on is not to inform themselves about the reality of anything they’re debating about. One possible explanation I can think of is that there are better ways for people who are actually trying to help solve the problems, to get ideas and encouragement from each other, which could be why I never see that happening in Internet forums. Maybe Internet forums are strictly for social interaction, and bringing reality into the debating would spoil the RPG.
Ok, having read the OP again, perhaps I'm understanding your question better. (But I might not have this right, so bear with me.)
I spend some of my time on this forum for a few reasons:
1 - I DO want to understand some issues better. I think debate can be a good way to understand issues better, and I have learned valuable things from the debates I've had on this forum.
2 - I think conversation and debating are valuable skills, and I think I've learned some debating and conversational skills while on this forum.
3 - As my tagline indicates, I think we are making a positive change in the world when we call things by their proper names. For me, a common reason to debate on this forum is to try to reveal the proper names of contentious issues. For example, I think that the real issue in US politics these days isn't GOP vs. Dem or liberals vs. conservatives. I think the REAL issue is the impact that Oligarchs are having on our democracy. So to me, the "real name" for our political issues is "oligarchy". And I think that if more people knew that, and used the term, we'd be starting down the path of real social change.
