Your characterization of a loving interaction between these two women as "abuse" is typical of the oppressive, heterocentrist, homophobic attitudes that plague our vibrant, diverse society. It's precisely attitudes such as this which have caused so much grief in the world, including but not limited to the resistance to gay marriage and the closure of bath house facilities throughout much of North America. As to the "parents" (biological birth-givers) they should have no say in the matter because all parties involved are sentient beings and influencing their natural behaviors in any way is tantamount to a rejection of the entire principle of Diversity and Progressive Change.
You sound like one of those evil "conservatives" that I've read about in The Nation, Pravda and The Worker's World, and your words constitute Hate Speech. Prepare for imminent arrest and reeducation in the Homosexual Diversity Indoctrination and Reeducation Gulag where your mind will be cleansed of all thoughts hostile to the Homosexual Agenda and Forced Diversity through continuous screenings of "Priscilla, Queen of the Desert", "Oprah" and "Ellen" reruns and repetitive readings of "Heather Has Two Mommies".
You will be assimilated to The Collective, there is no escape.
