This is typical Alinsky tactics. They want to "debate" the issue because they want to talk us, literally, to death.
"No" is a legitimate response. If they won't listen to that, "HELL, NO!" is also appropriate.
There is no debate — they are NOT listening. Watch the interview Greta Van Susternen (sp.) had with Sheila Jackson Lee last night about using a cell phone when a citizen was politely asking a question. Not only did she NOT admit she was wrong, listen to what Greta was saying (it was perceived as extremely rude and discounting), she “jammed” Greta and wouldn’t let her get a word in edgewise.
