edit And then I get downvoted for sticking my neck out. Let me break the parent post down.
It asserts that charging genders equally will shift more burden to women. This is clearly true because premiums are higher for men because we have more accidents (so much for all the female driver jokes).
It also asserts women were a previously disadvantaged class. Also clearly true.
So to the downvoters out there, you might have found something disagreeable about the parent post, but you're wrong and he's right.
