They hate us, because we’re not Muslims. They would hate us, even if we had social customs like theirs. They would hate us, whether we were moral or not.
Hate develops from envy, which develops from vanity/pride. People hate and envy because they think too highly of themselves. On the plus side, this defect of human nature is the source of a special environmental pressure that drives human genetic and cultural evolution at high speed. Those that hate tend to end up getting removed from the gene pool. Unfortunately the vanity bell curve spontaneously reforms with one half of people envying the other half, so the cycle repeats endlessly at a self-regulating pace.
