You can deny the categories all you want, but that doesn't mean you don't fall into one of them. Ideology does make a mess of things, but that doesn't mean that the causes gripped by ideology are incorrect. (On either side.)
No one group of humans has a monopoly of being 100% free from bullshitters. There's a large group of mostly silent atheists who are perfectly reasonable, just as there are groups of less-silent lunatics.
True enough, but this observation cuts both ways. There are also large groups of mostly-silent religious people who are perfectly reasonable, to a point. Like the atheists, however, many religions allow the prudentialists, perfectionists, and guilt-trippers to shit all over the place. No thanks, to both of them.
I mean, say what you like about the tenets of National Socialism, Dude, at least it's an ethos.
At this point in time I'm more interested in the experiences of living and learning. I don't care enough about "ultimate" questions or answers to accept or reject them. I don't need to be right about this; tomorrow I might decide to be a hardcore fundamentalist X, for any value of X. When I talk to friends and family who have beliefs (or not) of any sort, I try to emphasize the good parts of their systems: those parts that seem the most likely to help them in the ways they need help. I also critique those concepts that don't seem likely to help, but only for that reason, not because they're "true" or not.
I've probably said too much; this is really off-topic for HN.
