I'm a London-based rationalist, secularist, humanist, believer in reason and evidence. We have an excellent and growing community of active non-believers who can freely promote and indulge in science, culture and moral codes based on experience and contemporary society. I'm so lucky to be in a place where we can do this unhindered. We have many prominent humanists and secularists in science and even in the upper house, and post-God Delusion, this is growing exponentially. It shocks me at how resistant the americans still are to the concept of atheism (godless is such a dirty word there), and the experiences of people elsewhere, like Raif Badawi, shows that we still have a long way to go in other parts of the world. And a fortunate side-effect of this is we don't have the religious nut-jobs who blame the floods on same-sex marriage or preach about impending raptures. We do have one guy with a megaphone but he's been ASBO'd into submission. Our classrooms are largely secular and creationism isn't enshrined into the cirriculum to give a balanced view-point. In my experience, many indigenous Londoners and Brits are non-religious - it's very rare to meet a committed Christian, especially of the younger generation. The people I come across who are religious tend to be 1st or 2nd generation immigrants who believe in non-Christian religions (I myself am a 2nd gen immigrant born into a very small religion). A huge part of it is cultural. Religion doesn't play an important part in British culture, hence the disinterest and agnosticism from such a large proportion. Festivals such as Christmas and Easter have become so secular that they're equally celebrated by most people of all backgrounds, and the enduring traditions such as Santa, presents and chocolate are not taken from scripture. Outside of the major festivals, which are cultural more than religious, many people only rely on the church for births, weddings and funerals. The church wields little power, and that's a marked shift from recent times, where they were able to ban films like Life of Brian and influence other aspects of our lives and laws. There are conflicting stats here (from the census in 2011 and an annual in-depth study into British culture called the British Social Attitudes Survey (this article uses 2009's info)) https://en.wikipedia.org/wiki/Religion_in_the_United_Kingdom The reason for this disparity is partly because non-practising Christians, who make up the biggest segment of the UK's population, are sometimes pained to commit fully to irreligion. So in practice, the number of people who self-identify as Christians is inflated by this issue. I see big shifts towards humanism, atheism, agnosticism and irreligion in the next generation, both here in the UK and in other countries such as the US, Canada and most of Europe.
