Hate is a strong word. I don't really hate this song, I just strongly disagree with some of it. Sure, I agree with peace and a unified world and such, 'cause as a Christian, that's what we should be going for, right? However, the way Lennon describes it doesn't sound so wonderful to me. No heaven or hell? no religion? nothing to kill or die for? We need purpose in out lives, and without it life wouldn't even be worth living, even if it were in a peaceful world. Having a life without meaning sounds worse than living in a world with problems.
