I agree, it is just that sometimes people may actually get in trouble with the community as a result of being offside on the rules. When the rules are somewhat opaque it may make it more difficult for people to judge what is allowable until after the fact. That was why I had believed that political discussion was broadly disallowed.@amirm has - in this particular case - just told us. In others, the mods do.
I'm good with it though. This is Amirm's community and we're guests so ultimately if he is comfortable why should I have a problem?
