Paul Graham on Small Identity
Paul Graham explaining how politics becomes ingrained as part of people's identity.
Then it struck me: this is the problem with politics too. Politics, like religion, is a topic where there's no threshold of expertise for expressing an opinion. All you need is strong convictions.
