It's that ingrained misogyny that women mustn't have anything of their own until they've provided the same thing for everyone else first.
We get less of it now - the misogyny has changed shape a bit - but I remember when it was all fields around here the several posts a week on MN demanding how dare MN be providing a forum for mums, it was sexist, what about dads? Where was the dads forum eh? Eh??! Allabunchofmanhatingfrigidotherwordstoo....
To which people used to very politely point out: MN has a dadsnet section (very little traffic), which the moaner hadn't bothered to look for and certainly didn't want to actually use, and there was nothing stopping men from creating their own parenting forum if they wanted to. No one has wanted to. Pistonheads is probably the best known mens forum but parenthood isn't the driving centre of it.
It was all about 'how dare you have something you haven't first given me the lions' share of'. Plus ca change really. The same attitude underpins all that the HoL were discussing.
