If a subreddit forbids discussion of a topic, you probably wouldn't have been able to have a good conversation about it anyway. Don't go to the biggest subs! Avoid the places that have been taken over by the most aggressive enforcers of mass culture! Reddit's great redeeming virtue is that it's big enough for groups with more liberal discussion norms to flourish, if you can find them.
Yes but downvotes are annoying and the sub threads aren’t a good place for real discussions imo. I’d take an old fashion forum any day. It’s a shame that outside of history and science fiction there aren’t too many large forums anymore as Reddit has basically replaced them all. Reddit has a serious meme problem (even on subs where they’re banned) and repetitive jokes often times derailing conversations as funny one liners get upvoted to the top (then replied to with funny one liners) as longer form posts get moved to the bottom.
