Yes, all that makes sense to me. It's not scientific, but in my experience, folks I have encountered who have done and said things that "devalued" pregnancy, childbirth and mothers in general, have most certainly not been feminists.
I remember once being asked by a guy why there were Lesbians involved in reproductive rights and childcare campaigns. For starters, he wrongly assumed that Lesbians would never require reproductive health services (e.g. sti prevention, gynae cancer screening, sterilisation, fertility treatment, etc.) or be in a parenting role. However, for Lesbians who are feminists, even where they might not personally require these things, are capable of thinking way beyond what is in their own immediate interests!
Yes, I also think MRA folks also peddle the idea that Feminists hate mothers and motherhood and are quite partial to consuming the odd toddler for their tea!
