Pursuant to this, I would like to recommend that Dr. Williams be removed from any and all positions of authority and seek psychiatric help. A perfect example of someone whose beliefs are crazy—suggesting that people should, basically, be able to pick and choose whether they follow the secular law or their religious law.
Uh, no. Everybody follows the laws of the country they are resident in. If they also choose to subject themselves to religious law, that’s their problem, but that doesn’t excuse them from also following the secular law. If I was to start a religion that required adherents to perform human sacrifice, even the most ardent proponents of religious tolerance would not try to prevent my prosecution, and rightly so. The fact that it’s a religious requirement does not change the fact that some things are just wrong and/or crazy.
(Note that I have no problems with anybody choosing to follow Sharia law, Jewish law, or anything else, assuming that it’s entirely within British law. However, given that Sharia law apparently requires the death sentence for certain crimes, I don’t believe that it’s possible.)
More generally, the fact that some people "do not relate to the British legal system" is something only an utter lunatic would use as justification for excusing said people from the law; usually, people who do not relate to the law are referred to as "criminals". (Of course, if the law is wrong, then it’s justifiable; an example would be laws against homosexuality. There is, however, no evidence given that the laws are in any way unjust; it’s merely that some people don’t want to follow them.)
In essence, it appears that although non-religious people have to respect Christian rules (the supposed "sanctity" of marriage and of life, as far as same-sex marriages, abortion, and euthanasia go), religious people don’t necessarily have to respect secular laws. This is heading worryingly close to noted Christian nutjob Mike Huckabee, and his claims that it’s necessary "to amend the Constitution so it’s in God’s standards…".
Update: An interesting reply to Dr. Williams’s comments.
