Learning to let go of ideology is perhaps the greatest lesson I've learned, it allows me to think freely (kind of like atheism really).
If you actually think that... then... well... I'm afraid that I have some very bad news for you.
Okay, maybe not the greatest lesson I've ever learned (brushing my tongue while brushing my teeth to give me fresh breath is probably the greatest lesson I've ever learned), but it's up there.
Obviously, not being beholden to a consistent pattern of thought has it's benefits. You don't ever have to defend something for being "not (insert x here)".
