I don't have confidence in polls, but they have a little bit of value and are often interesting:
Most Britons describe themselves as Christian despite not attending church regularly, a BBC survey has found.
The poll taken for BBC News 24's Faith Day examines how belief in religions is shaping British identity.
More than two-thirds of the 1,019 respondents said they were Christian, but only 17% regularly went to church.
Almost 75% of respondents said the UK should retain Christian values - including 69% of Jews, and nearly 50% of Muslims, Sikhs and Hindus.
Link.
I really liked this result:
A fifth of people polled say they feel less positive about Islam since the London bombings on 7 July.
Really? The other 80% couldn't hate it anymore than they already did? Or are they hopeless relativists who couldn't feel less positive about any idea/religion/philosophy even if it burned down their house and decapitated their own children? I'm guessing the latter. Of course, they may not attribute the bombing to Islamic beliefs, in which case they're simply delusional.
