How's this for a counter-example? Orchestras used to have a ton of reasons why women were grossly under-represented -- they just weren't interested, they didn't have the skills, they didn't have the long-term ability -- whatever. But when orchestras started to have players audition behind curtains, suddenly a lot of talented women started getting hired.
Right now there are plenty of teachers who literally don't want women in their high-tech classes. This bill helps solve that problem, and doesn't let the teacher weasel their way out with cop-out answers.
