That's the other thing you can set your watch by: disagree with the 'whinge' party line and you must be a private pilot, a failed airline pilot or management!
No need to be rude , 6000PIC, I freely admit to getting tired, especially towards the end of a second consecutive night flight (yes, I was charter for 15 years, Random) but it was never anything a good sleep didn't cure. Last time I was 'fatigued' was after three days without sleep at a military winter survival school in -20C and a tent!
