I'm betting against that "idiot" thing. I HATE presta adapters. Here's why:
If that little stem on your presta valve gets bent, even a little, when you try to screw the presta adapter back on, it also screws that little nut back down. Now the valve won't open again.
How do you normally pump up your tires? If you have an air compressor at home, drill out your rims to accept schrader valve inner tubes. It's much faster and easier and my schrader chuck has a built-in air pressure gauge. If you use a floor pump, presta is easier so set up your pump for presta and pitch the adapters.
