Mostly likely a latent cultural influence of Anglican moral code. I'm sure he'll see the error of his ways once Sharia law dominates in the UK. After all, The Prophet married an eight year old in his 50's; what right does he have to intervene when the law says that a man of the Koran can take the child daughter of an infidel such as himself?
