A friend's partner had a baby and said friend sent pictures of the family to the gay-lesbian-bisexual-transgendered email list community we were a part of. Now my friend is African and Native American and is very very dark indeed, but her partner who is African and European, appears European, as did the infant at birth.
Not a single person responded with any congratulations. Then a week later, an European/European American lesbian couple also had a baby. They too sent their pictures to the mailing list, and within 10 minutes the mail was sent, a barrage of congratulatory emails was flying from the gays and lesbians on the list.
At that point, I wondered why there was such a great disparity in response, but what can I prove?
