People don't conclude that the gap results from wage discrimination without help. The gap is actively spun as if the only possible conclusion for it's existence is discriminatory practice. 

Witness the Prof cited in yesterday's piece saying it's "outrageous" that the gap is this bad, in Canada, in 2017.  It's clear we're supposed to walk away with the concept it's a moral outrage this is occurring, but choosing to work less isn't morally outrageous. Neither is choosing work that's flexible for families. Neither is choosing work that's safer, even if it pays less. The only morally outrageous option is discrimination.

It's still fake news. Misrepresentation to suit an agenda is still fakery.
