I object. I don't give the slightest of fucks what plumbing my plumber has. I care if they can keep my toilet flowing.

Nobody gives a shit what wedding tackle their truck driver has. When I was in CDL school, my primary competition for the #1 slot in the class was a gal, and I certainly didn't dismiss her just because she had a rack, because the only thing that mattered was who could back the damned truck up in a single maneuver.

But I have been to trade school four times since I got my CS degree, and the only field where women even came close to matching male participation was in EMS, and even there it was like 25%, as opposed to 5%.

EMS occasionally requires actual mass. Welding, machining, and truck driving don't, but women never go to school for those, based on my experience.
