Pink News, Europe’s largest gay news service, reports that Apple has approved an anti-gay iPhone app:

The app is based on the Manhattan Declaration, a manifesto released in 2009 by Christian and Catholic leaders which rails against the “erosion” of marriage.

Apple has given the app a 4+ rating, meaning that it contains “no objectionable content.”

The app asks users whether they agree with four statements on abortion and same-sex marriage and those who answer that they are pro-choice and pro-gay marriage are told that they are incorrect.

It also has links to read and sign up to the full declaration, which says that gay relationships are “immoral” and that same-sex marriages are equivalent to sanctioning incest.

Change.org has launched a petition calling on Apple to remove the app from the iTunes store. To sign the petition, go here. View more screenshots of the app at Good As You.
