Use of Generators to run Air Conditioners when camping

So far in my travels I have never seen anyone holding a gun to a 'generator hating' camper's head at the entrance to a CG that clearly states Generators Allowed, and 'forcing' them to go into that CG.

So for me I find it very sad to see all the derogatory statements towards fellow RV'ers that use their generators in compliance to the CG rules where they are parked with their RV.

Post after post telling campers NOT to follow the CG rules.:?
