No need to be rude, fatigue and sleep management is a factor in ATC as well, so I'm very well aware of it.... and even I've put in that call. (Even told my friends that the flight we arranged had to be postponed.... cause I was tired).
The question was a "devils advocate".... but I think I'm sticking my hand into a bee-hive here.

Agreed.

Agreed, but you'd still not fly if you were tired to an extend a cup of coffee couldn't solve it, so "tired" is also an valid excuse. But I bet you most people have no quarrels if they are on their way home, jumping into a car and driving while tired, though they shouldn't.
