Skeptics in the pub sounds like fun.
The London group regularly holds pleasantly booze-soaked meetings about à la mode secularist obsessions: conspiracy theories, superstition and alternative-medicine. Since I enjoy a bit of verbal fencing with my ideological opponents and seeing the horrified looks on their faces when I inform them of the sorry history and present day extremism of contemporary "secularism" is always amusing especially if there's some ethanol around to loosen things up a bit, so I might check it out one of these days.
But gosh, doesn't it sound achingly middle-class:
"Argumentative types – scientists, academics, IT consultants, librarians and a light seasoning of lawyers – crammed into a room above a pub, on a sticky summer evening, wouldn’t do it for most people’s blood pressure. On the other hand, if Big Brother is ruining your summer, you might prefer this."
