Legislation means you arent allowed to mock or belittle people based on their religious beliefs, sexual orientation or ethnic grouping.
If you rewrote the Quran to have Mohammed as a paedophile you'd get locked up, if you riduled a gay for being gay you'd get locked up and the same should apply to those rewriting the Bible into a pinker version. Its inflammatory, its disrespectful and its mocking the Christain Faith.
If you want more respect from society they you have to show respect to those with religious beliefs too. Its only fair.
