If that were the case, if that rule were strictly enforced, there would be hardly anyone at all posting in Spray.
Do you remember Mtn Goat? He was a conservative who tended to make long winded posts and always attempted to argue his points logically and politely. Others would heap insults on him, but he never played that game.
Ditto JayB; master of tongue-in-cheek. Despite my best efforts to get him to take off the gloves, he continues to let j_b's insults, name-calling, and cheap shots roll right off. Yet more evidence that playing nice gets you nowhere with rusty tools on the hard-left--so why bother?
