I have never visited a "mommy support" forum before but I doubt they are there to bash women who have made the decision to remain childless. If you came to this thread to discuss being "CF" then why not discuss that and what you do rather than bash other women?
Maybe you should read a little more widely, becky, because sites like this exist for a reason. We get a little sick of being called, on mommy sites and to our faces, "sterile", "barren", "heartless", "screwed up", "selfish", "self absorbed" and on and on and on. Just because we've made the decision not to have children, a surprising number of people find that offensive and assume it's their right to tell us all about it. So this is our little haven, where we can come and talk to other people who totally get it, because 80% of society doesn't.
Human nature being what it is, you dis people, you should expect to get dissed back. We get dissed a lot. Unfortunate, but true.
It's also unfortunate that women in particular just can't seem to be supportive. Mothers bash us, but they also bash each other, and it's pretty sad and pathetic.
Just for a laugh, you could try this - go and post on a parent site and put the word "childfree" in there somewhere, and watch the vitriol start to fly. I think you'd be truly shocked.
For myself, if I don't like it, I don't read it. I don't go onto parent sites or baby sites or religious sites, because I know I'm not going to like what I see, and it doesn't really matter to me anyway. Live and let live.
