What does book burning look like in the 21st Century?

This:

A petition has been started to ban a ‘gay cure’ group’s iPhone app.

Christian group Exodus International claims that people can find “freedom from homosexuality” through prayer and practises conversion therapy.

Its iPhone app, which is free and available in the iTunes store, is “designed to be a useful resource for men, women, parents, students, and ministry leaders”.

It has received a 4+ rating from Apple, meaning it is deemed to have no objectionable content.

More than 6,500 people have signed a Change.org petition to call on Apple to remove it.
