Apparently r/logic mods have decided a political issue is so important that they need to hold a subreddit with 25k members hostage, whose subject matter is completely unrelated to the issue.

Please be civil. No personal attacks. No name calling.
No commercial activity. No ads. No promotions. No fundraising.
Relevant posts only. The post has to have something to do with the subject area of logic.
No duplicates. A repeated post may be removed. Please try to keep a discussion on a single issue within the same post.
No empty posts.
Openness. In general, no post, comment, or member shall be removed, except for a serious and compelling reason. This subreddit is public
