You mean like the stereotype that the military pilot is the one hitting on your wife.? Posted by a military pilot.
The point is that there is a perception among civilians that military pilots don't think we've sufficiently paid our dues. Many of us have been berated many times like this, especially by double breasted pilots in a jumpseat or while jumpseating.
So when we get a military pilot who we perceive to be talking down to us, we go into "here we go again" mode and flame right back. Salt in the wound from years of being told mil pilots are better, despite their overall lower flight time, because they got shot at. As said above, most of us risked our lives to get here too.
