No politics. Seriously, none. No getting around the rule by referring to it and covering your ass with [zomg politics!] either. No statements, however balanced and fair you may think they are, which allude to current political matters.
Seriously, this is not a hard rule and we are perplexed at the frequency with which y'all are breaking it. So this is your warning. No more tiptoeing around the line, because you will get banned (or worse*) if you do.
*Yes we have found worse things than banning.
