If you have no balls to take your responsibility towards your first priority at all times, safety, then please get out of Aviation
You can't use the safety argument all the time. If you took that argument to it's logical conclusion then you would never go flying.
The fact is that flying for an airline always will be a compromise between safety and commercialism. Just getting airborne degrades safety, where do you draw the line?
Most airlines do now have a fuel policy but the decent ones won't question you if you add a bit extra when the weather is bad etc.
PLOG fuel will provide enough fuel to do the job under normal circumstances. When circumstances are compromised then take some more.
