It's not a popularity contest, and most Brits not being religious means that sort of result is about what you'd expect. The nonreligious ones are going to think religion is, at best, unnecessary for morality. I'd like to see the UK's prison statistics by religion to see if there's any difference in proportional representation. I know the representation of atheists in prisons in the USA is remarkably low, but I expect that's partly an artifact of US culture being such that atheists have to be atypical to buck the pressure to conform. Where it's the norm, their prison representation should be higher...but is it as high as prison representation from religions?
I'm not anti-Christian. I'm anti-stupid.
