"There's probably no God. Now stop worrying and enjoy your life."

Hm, that "probably" bit doesn't sound too convincing. I suspect it was written by an agnostic moonlighting as an atheist. I mean, if you consider yourself an atheist then shouldn't "There is no God" be the correct statement? "Probably" is someone saying I'm not quite certain so I'm going to hedge my bet both ways. You know, just in case.
According to the
article in The Guardian, the campaign is designed to "counter the religious ads running on public transport" in the UK, and has raised 11,000 squid [with a contribution from Richard Dawkins].
I'm not sure this is a wise use of money, particularly when the economic outlook ain't too flash, homies. Besides, if one is secure in their beliefs -- either as a believer of God or a non-believer -- then the opinions [or advertisements on a bloody bus] of others who hold beliefs contrary to yours shouldn't get your knickers in a twist. That would just be silly.
I'm not surprised
The Guardian is involved in this. I like
The Guardian, but sometimes they try too hard to be the poster child for the left-of-centre crowd. They reached their nadir in this regard during the 2004 US Presidential race when they ran a campaign dubbed
Operation Clark County.
The Op called for UK readers of
The Guardian to write a letter to people in Clark County, Ohio, to suggest they vote for John Kerry and not W. As one can imagine, it went down like a
lead balloon. And that's hardly surprising. If I got a letter from a random Aussie telling me who to vote for I'd tell that Ocker to fuck off, and fast. That kind of shit ain't cool.
All aboard.
