It seems to me that if you write an article about parenting and keep talking about how "fathers" can help "mothers," and link that article to a page on your website titled "Help for Fathers," it's great that you see parenting in mixed-gender partnerships as a team sport BUT you really can't claim -- in a footnote! -- that you "acknowledge the diversity of families" because you suggest that "at any point ‘partner’ and ‘she’ can be substituted" for "father" and "he." →
Either write the thing as gender neutral or don't, but relegating same-sex partners to a footnote and asking them to do the writing work you should have done does not really show a great deal of commitment to acknowledging that not all families fit a single mold.
Especially since it's written by a licensed social worker (who should know better) and directed at mothers with post-partum depression (who already feel isolated and and misunderstood).
Bah, I say.
