"She took a baby from a potential mom and dad. bottomline."
I do not have to approve of Ms. Cheney's relationship to know this is sheer balderdash.
How did she "take" a baby from anybody else? What baby did she take?
The obvious fact is, there was no baby to "take." This is not an adoption or a surrogacy -- she is carrying the baby herself. She was inseminated in some manner; probably by artificial insemination, possibly by actual intercourse with a male partner (sometimes lesbians have been known to do it that way.
When the baby is delivered, it will be from her & will be hers -- no other couple will be "deprived" of a baby. Unless you think there is only a limited amount of semen in the world and that the small amount of it that has impregnated Ms Cheney would otherwise have gone to some other woman in a heterosexual union?
A baby, child and youth deprived of a Dad by selfishness and zeitgeist. Two women, incomplete, by choice. A child, incomplete, without choice.
Who is the fool that was the donor, and why?
