Hithere
Feminism is about supporting each other as women.
Saying that sahms (stay at home moms) are foolish is not being supportive and judging all marriages by the same slate.
I think it is partly that Hithere. However, I am sure that there are some women whose choices you do not approve of. Sex workers maybe. Or possibly unemployed single mothers. I feel that way about women who allow themselves to be dependent on men.
It isn't a judgement on marriage (I will address THAT one later). It is an acknowledgement that women are adult human beings responsible for themselves. Most westerners marry for love. Love doesn't prevent you from needing to think about the future. No one is doubting the love that people feel when they marry. But almost 50% of marriages end in divorce. THAT is a cold hard fact.
If you marry a man with the intention of not working, you are in effect entering into a patriarchal arrangement, wherein you sell yourself to him in exchange for financial gain.
I have two friends who have in particular been devastated by falling into that trap. One is now stuck in a tiny apartment, having to work at a job that is hugely beneath her abilities, but having no training to do anything else. A virgin at marriage, to a man of high standing in her church. The other, married again for love. Stayed at home to raise the children. Divorce once the children were in their late teens. She is in an even more menial job. We were at school together. She's a lovely, kind, honest, genuine person. Life wrecked through financially depending on someone else.
Feminism is about equality. There is no equality in giving away your security to someone else.
