Chil, a lot of us on here spend significant amounts of time doing voluntary things and always have, so I am not sure your comments were well directed.
I think what concerns most women is the idea that they are now going to be deprived of hard won jobs and financial security and expected to do voluntary work for free all the time instead, at the behest of other people. This might have been OK in years gone past, but society is radically different now and it would mean real hardship for any women whose bloke died or turned out to be less than responsible.
It would also mean that educated women would be required to leave their brains at the door upon marriage, which is indeed what used to happen. There is a great body of opinion, including very many bank of England reports, that argues women's participation in a life outside the home and in the workplace was a significant factor fuelling economic growth over the last couple of decades. So even if one individual woman chooses to stay at home, we are more or less relying on her neighbour next door to do the opposite in order to ensure the prosperity of the rest of us. If we all stay at home, society as a whole will be substantially less affluent and prosperous, and ironically children overall will be less well served (even though some individual families in some social groups might feel less hassled).
