Bull. That you personally haven't stated that people are "traitors" doesn't mean I haven't read it here on this very site and on others we participate in.
People enjoy "turning the tables" but I even read it early on. People would say things like, "As far as I'm concerned you are the traitor and un-American because you don't 'support the troops' with blah, blah, blah..."
Saying that such sentiments haven't existed doesn't make them go away. Those getting called that more regularly haven't much to 'apologize' for, it is a tit-for-tat arrangement.
