This same-sex couple has been together for six years and live in an English Zoo and now they have adopted an abandoned Flamingo chick. They are Flamingo's themselves, so one would think it should be fine for the gay Flamingo's to adopt. But as Andrew Sullivan points out they are engaging in what the Vatican calls an "intrinsic evil."
How does the Vatican know caring for and rearing a chick that might otherwise perish is evil? Because natural law says so. Meanwhile, nature seems to be ignoring the voice of God, as interpreted by the Pope. Time to excommunicate Planet Earth? Your Holiness, standards are slipping.
