Flying is risky enough at the best of times, so anyone who doesn't try to minimise that risk deserves everything they get, in my view.
All I know is I'm glad I'll never be flying with you
This thread should really be in the Private aviation column as the tech forum is really meant for professional pilots dealing with issues in commercial aviation.
You sir have not idea what is appropriate for the commercial operation of piston engine aircraft. I can say as a professional pilot that the pretty much universal practice is to do a full runup at the beginning of the day and then only do a runup if there is cause for concern . The logic is that pretty much everything that the runup will tell you will be observable while flying on the previous leg and therefore normal operation on the run in obviates the need to do a runup. To imply that every pilot is acting unprofessional for not doing a runup before every flight speaks more to your lack of knowledge than anything else...........
