Humanism is morality that transcends religion and spirituality, not the opposite of it. Atheism is merely a religious paradigm that matches quite well with humanism, because atheism asserts that nothing divine has dominion over the way we should act as sentient, free-willed beings. However, I still agree with the intentions of the OP, which are to tell us to awaken as a collective species and realize that we are all the same, despite our differences. Let's stop trying to create a utopia by killing people that disagree with our perspectives on what a utopia is, but rather working together for the ultimate and unachievable goal of a perfect world. We don't need 100% perfection to be happy, because most people in the world today will be content with many of the menial things most of us in developed countries take for granted. Just give it a shot.
