Seriously? I thought the default assumption was that being rational was harder. Working out your ethics and morals in a gray world, digging through philosophies to find meaning - it's a mess. I would be MUCH easier to believe what was pushed at me. If there were some kind of awareness after death, I might feel sorry for all those who wasted their time, but I suspect that most people do/have religion because it works for them. I really don't see a lot of people who are actually trapped by their beliefs. Hell, there are probably more rationalists in that situation - reason is a harsh master.
