I thought for sure it was Curves a few years back, but I searched for it and came across a blog from 2004 whining about Curves allowing transgenders.

This woman whines about a San Francisco Curves letting in transgenders (it's San Francisco for fucks sake!) and asks if "real women have rights anymore" due to transgenders actually having some rights. She also seems to imply that some are men just wanting a peep show. (and her picture in the corner made me laugh even harder at the idea of someone wanting peep at her)
