This line of reasoning, always strikes me as rather idiotic.

It's often heard from the progressive side of politics, in this general form, as if having everyone equally affected by bad things is a useful policy aspiration:

"<thing>, which is bad, disproportionally affects <girls, poor people, non-white people, etc.>, which is an outrage!"

Apparently, it's easier and more popular to make sure bad things are fairly distributed, rather than reduced or eliminated.
