This is the most annoying argument ever. The issue is not whether he made the right decision or not. That's not even relevant and not for anyone to decide except for the captain himself. Least of all any monday morning quarterback on this forum. These are the same people that, if the flight had ended up in an accident, would condemn the captain for taking the plane. With monday morning quarterbacks, it's damned if you do damned if you don't. Like the OP stated, the problem is that this captain exercised PIC authority and got suspended for it. Why any pilot should argue whether this was justified or not is truly appalling.
