The parent comment believes they have that problem solved by suggesting breast pumps (and formula, one supposes), but those don't work well for some people. To be fair, breastfeeding doesn't work well for some people and is part of the reason wet nurses were more popular in the past.

My larger point is, we shouldn't throw the traditional gender role baby out with the breast milk bath water. People have different preferences / requirements, and they should be allowed to make the choice to conform to traditional gender roles if they so choose, rather than forcing a 50 / 50 split of parental leave where there is some clear biological differences. The obvious ones being men lack mammary glands and uterus / ovaries.
