Clanad, Gently, of course, but here goes. I can walk past the Brussels sprouts freezer in the supermarket - I am not obliged to buy them and eat them . Similarly, I can walk past a church or a mosque and ignore what's going on there. Nevertheless, unlike the (delicious) Brussels sprout, religion's roots reach out far beyond buildings, and encroach upon all our lives. In that we don't have a choice. And quite honestly, I think, using that analogy, the same applies in the USA. As Supernick says, the chances of a self-professed atheist becoming Prime Minister or President are, at the moment, pretty remote.
By the way, Quinlad, the law on blasphemy, has, I believe, been repealed.
