These threads predictably always go the same way... (this is why the OP set the ball rolling, obviously).
People will obviously get super-defensive if their parenting is called into question. People will equally get super-defensive if they are called dim or 1950s or whatever.
It just goes on ..., and on ...., and on ....,,
There is no winning this argument because this issue is -
A) instinctive
B) economic
In the case of A) - not all women feel an instinctive need to be around for their children day in day out, so they can’t comprehend that some women really do. This also applies in reverse. But nobody can tell someone else that their instincts are wrong, can they? So it just goes on....
Then, in regard to B), the bottom line is that some families need two incomes, some don’t. Some women have to work, some have the choice not to. All our decisions are made in specific contexts and, in another relationship / set of economic circumstances, we may well have made different choices.
So the only thing anyone is qualified to comment in is their own set-up. You can have no idea about where anyone else is coming from.
In real life, nobody gives a hoot about anyone else’s childcare arrangements or work-life balance.
