If you're on Facebook, I can recommend a couple of maternal feminism pages.
It is a MASSIVE red herring to say that feminism is about choice for the reasons Buffy and others have stated.
I think one of the reasons that SAHPing became viewed as "not feminism" was because many first and second wave feminists fought to be allowed to work, to continue education and have that education recognised officially. They fought for properly regulated childcare, maternity rights, workers rights and remuneration and they did this in a much more overtly patriarchal society. The only option open to most women was to have children and stop working, or have no children and be allowed to continue to work. Even for working class women, the majority of whom went into service of one kind or another or, if they were lucky, shop work had to stop, often on their marriage. The military and Civil Service discharged women who became pregnant until relatively recently. Social mobility for women who had children was severely curtailed, and so feminists fought to change these things, but I don't believe they fought to change them so that everyone was forced to work when their skills and inclination lay elsewhere. The 'woman who has it all' meme seems misogynist as hell to me, because what it really means is that the woman DOES it all.
There are obvious cons to being a SAHP. Your CV suffers, however, as Lurcio has pointed out, this is easily surmountable with a change in business ethos. When your CV suffers, you are at your partner's mercy financially should anything go wrong. The fact that married women are better looked after by the law when relationships break down is merely another hangover from our paternalistic past, and is something that maternal feminists are looking at.
Feminism is for and about women, and because women are the sex class that becomes pregnant and has babies, then it also has to be about children.
I am a feminist. There are those who might suggest I am a fairly scary one
I do try and make life decisions with the welfare of myself and other women in mind. I have made some decisions that make other feminists' toes curl. It's not a cult, it's a political movement.
I've seen you posting Petal, and nodded along to a lot of what you've said. It would be lovely to see you post here more often.
