I take your point, and would not say that one "awwww ****" should undermine all the "aaataboys".
But this was not an "awww ****". This was a "f@Łk you!"
Chester Nimitz did indeed run a ship aground and that's a CM offence. However, i imagine he did not do it intentionally with the full understanding of the fact that it would end his career.
This guy was dumb enough to 1) do it in the first place (knowing that if he was caught then he'd be sacked) and; 2) Brag about it and show off. He deserves to be sacked for stupidity alone.
