I don't want to read the article just now because chances are it will wind me up just before bed. (am in Oz, not weird)
However - my version of feminism, as others have probably already said, means that I have the choice to be a SAHM without being written off as a human being, without being looked down upon by other people or having other people otherwise denigrate my choice.
I worked for 25 years, then I had DS. I choose not to work outside the home now. That does NOT mean I reject feminism - it means I have the choice (and am lucky to have it). What I would prefer is for people to value my choice as much as they value returning to work - and I'm talking about everyone from the local busybody up to Government here.
