Generally, I have no problem with Joe Wilson saying “You lie!” during Obama’s speech in regard to “good manners” or “unbecoming behavior”. Manners and behavior are overrated. If Obama lied, then such protestation could be justified. What’s disturbing is Wilson’s apology:
“While I disagree with the President’s statement, my comments were inappropriate and regrettable.”
If you disagree, you don’t accuse another of lying, you state why there is disagreement. Joe had a chance to shed light thru his apology (i.e. bring proof of Obama’s intentional dishonesty), but proved the purpose of his outburst was disruptive, not honorable. Disruptive heckling is blurring the line between town-hall meetings and joint sessions of the United States congress.
