Posting on an internet site does not qualify you to demean a man who endured horrific torture at the hands of the enemy.
I'll borrow a locution from Arturo Toscanini: As a man of the military and a war hero, I take my hat off to John McCain. But as a man of the Senate, I'll put it back on ten times.
But, a fundamental disagreement over politics does not lessen what John McCain endured in the Hanoi Hilton.
