If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
But a rule like "don't ban people for opinions you disagree with" would also fit the bill, no?
That would be a horrible rule -- no one would be able to ban me for my ardent desire to eat babies alive. I mean, unless you have some equally perverted moderators...
