To talk a little about myself, I'm a die hard libertarian, and I've spent countless hours being quietly angry about all the collectivists out there that wants to ruin our planet. Recently I've noticed though, that this rock-solid conviction of the superiority of a libertarian society isn't really productive for me in my relationships with others, and made it harder for me to intellectually appreciate good ideas from people who doesn't share my view.
I think the reason for this rigidity in my beliefs was that in my late teens, I felt as if I didn't belong anywhere, and getting an ideology to die for gave me a (false) sense of belonging.
I can't speak for this Lisp guy or the musicians but I can only assume that we perhaps share some similarities.
