@edgarblythe,
I don't think that's a real risk. I'd be very surprised if you changed your mind, ed.
More generally, this particular video argument against the existence of atheists ('they all change their mind in the end') is easily dismissed by experience.
Also there's no telling how many believers lose their religion AFTER death... ;-)
What other argument was there in your vid? That men are biologically prone to transcendance and religion? That may or may not be true, but we are also biologically designed to rape and kill... Does that mean we should submit to our nature, or can we think a little more than that?
I'm personally not a big fan of materialism, and see room for a form of 'atheist transcendence' were minds would be valued more than bile. That doesn't mean gods exist though. It just means that all atheists are not necessarily materialist.
