It's Chinatown, Jody.
"Arguing politics gets neither of us anywhere, convinces no one, and is indeed a dialogue that can only become more ridiculous with repetition (not to mention more tedious). And it is not good for the Zone. I’ll be happy to discuss anything else with you, but not economics or politics. It only leads to hostility, harsh words and mutual embarrassment." - ER, September 28
Apparently the key problems are "argument," "dialogue," or "discussion." Or to be more precise, pointing things out someone doesn't want to hear. Not "good for the Zone." A political monopoly on opinions, as hostile and harsh as needed, seems to be just fine for the Zone.
