If you are a mom you are working, if you are a so called working mom who has a job and hand your kid off to a nanny for 8-10 hrs then you are not a mother.
This is an intersting psychological question: what drives certain freepers to be so maniacal in their scorn of all mothers who work outside the home?
Possibilities:
1) Envy. (They envy others with careers.) This would be sad, because staying home with a child is a noble career in itself, if you make that choice.
2) Defensiveness. They are sick of liberals and other people looking down on stay-at-home Moms, so they overreact and viciously attack all working mothers as a way of justifying their own choices.
3) They care about the kids. I wish this were the likeliest possibility, but this wouldn't explain the utter irrationality of their posts.
