People's beliefs rarely reflect how they actually live; I think that's a universal source of frustration for most people.
I'm not a nihilist though, because I'm not an atheist, I'm an agnostic. There are two types of agnostics: ones who don't think they can ever know if God exists, and ones who don't know but don't rule out the possibility that someday they might. I fall into the latter category. I also think there might be truth that exists outside the scope of science.
Either way, death fucking sucks, and I get really annoyed with guys like Harris and Dawkins who try to put this positive, humanist spin on it. I think deep down they know it's a bleaker world view, but you can't come out with that cause you're trying to rally people to your cause. It's all
PR nonsense.
