I too received the invitation from Change.org to sign the petition to get Apple to remove Exodus International's "gay cure" app from its store. Now Change has sent a thrilled announcement of victory: after 150,000 signatures, the app has been pulled. Although it's certainly sad that in 21st century America there are still people who think, or claim to think, that homosexuality is a malady that needs to be cured, it's also alarming that a business corporation like Apple is given the authority to decide what we can or can't view on our (their?) iPhones.
The inevitable consequence is to create a moral quagmire and situation of absurdity in which liberals are calling for censorship.
