Agree with a lot of what you're saying, I find the lack of empathy among nerds most frustrating (you know, snickering shouting 'DARWIN AWARD!' when some poor kid gets run over for doing something admittedly questionable), and see how it comes from a similar place as conservatives who blame all of our societies ills on the poor (instead of viewing poverty as a symptom).
I do fear the nu-Republican honestly - savvy, bright (at least technically savvy), and completely amoral now that religion's not there for even a hint of ethical balance. It's headed there, oddly triggered by the Gay debate partially (I think most young republicans just don't care). I just find it difficult to understand, isn't life just better when you view society as "US" vs "ME AGAINST THE WORLD!"?
