Stupid time to c-bet?

I C-bet most 50NL hands when I am the PFR, probably about 80% when checked to with position. Since, my c-bet can't withstand a re-raise here is this a stupid time or just an easy hand to get away from? Secondarily, how often do you C-bet a whiffed flop as a follow up to your PFR when checked to with position?
Villain sees 40+% of flops, so if he calls c-bet on this flop I shut down anyway.

Seat 2 is the button.

What percentage would you say you are C-betting when checked to after a PFR?

I almost always c-bet HU, unless I've got showdown value and want to catch some bluffs.

It's ridiculously exploitable, I know..
