Yes, I disagree with that. Or at least that it wasn't any more open than it is now.

Doesn't really seem like you have anything substantial on your side other than that you don't like t_d. I've shown you other subreddits that act the same and other subreddits that I think are more detrimental to rational debate on Reddit. All you seem to have is you don't like t_d because they ban people that break their rules. Rules that are similar to what other subreddits have had for years.

If you want to debate it show how t_d is different than SRS. Or how it's had more negative influence on political discussion than long time circlejerks like /r/politics. It seems to me when the main (and until recently default) subreddit for discussing politics is an anti-Republican circlejerk that has a more negative impact on rational political discussion on Reddit than whatever impact you are seeing from t_d.

Do you have any evidence of a change in discussion or impact from t_d other than that they banned you from breaking their rules?
