I agree with what some people said above. The song is sarcastic but not necessarily critical. Sometimes I look at it in an optimistic, figurative way where it's telling you not to hate, but sometimes (like today because I'm angry) I look at it literally and think to myself "I really do hate everything!" I think you're supposed to identify with it in that way when you are angry and it makes you feel better because you know there are other people who hate things too.
