Only when you're closed minded to other interpretations of the bible and the ongoing transformation of religions.
Tutu accepting homosexuality is not in contradiction to the bible or his religion. It may contradict your interpretation of the bible, and it may contradict the majority of Christian interpretations, even within his own church, but that is not the religion and he was not rejected for his interpretations, he was respected. He was an Anglican bishop and as such was part of a denomination that is accepting of homosexuality in many parts of the world, even if it's not everywhere. So no contradiction, he was not a lone voice in the church.

So where is the contradiction to religion?
The Bible says nothing about 'homosexuality' as an innate dimension of personality. Sexual orientation was not understood in biblical times.

Again, interpretations of the bible.
