GA pilot here. This is true and most of us don't like using leaded gas either. It's nasty stuff that leads to increased wear on our engines, is more expensive, and is increasingly used as justification for closing airports. Plus we're exposed to it when fueling our planes.

However, it's worth mentioning that recently the first unleaded avgas, G100UL, was approved by the FAA. We're trying to move away from 100LL (leaded avgas) and are finally making some progress on that front.
