Not sure what outfit you fly for....if "your" captains responsibilities and freedom in decision making are that restricted the regulatory agency needs to step in because the safety protocol is broken.
We, as a crew, still, decide the amount of fuel we take , decide to accept or not a maintenance write up/deferral , to continue an approach or abort, to accept an unsafe ATC clearance( yes it happens, been vectored straight into cumulus granitos in Equador) etc etc.
