If you or I were to take off a year to be a stay at home dad, would we suffer the same career consequences as women? If the answer is yes, then the issue is that we don't let anyone have children without harming their career, and that sounds counterintuitive and should be fixed.

If the answer is no, then bigotry is at play. It's impossible to know this answer, so we should just make it painless to take time off. I know of plenty of academics who go on sabbatical, fall off the face of the earth, and ignore every department email for a year or however long. This process actually improves their career, not hinder it. Taking time off is harmless.
