What has gotten my goat the most, as my life has progressed, was realizing just how ignorant a massive portion of the world is, for whatever reasons under their control or not and how much suffering ignorance causes. Surely, for example, you've realized by now that the various conflicts going on in super-poor parts of the world are mostly carried out by people who are very much characterized by things that go along with poverty, like being ill, uneducated, steeped in superstition of various sorts, unhappy, and surrounded by tons of crime. People still kill other people for... 'witchcraft'. As a result I've kind of stopped being terribly humanitarian.I think this reaction is partially unavoidable, because the world really is fucked up. To understand it fully is to realize how unjust and nonsensical it really is.
