Singer and Universal Love

Peter Singer is well known for adopting positions that call for such radical action in the service of others that he might be thought of as advancing a case for universal love.  After all, his ethic does not make much of a difference between caring for a family member and a stranger.  But one should bear in mind that while his utilitarianism leads him to advocate radical giving of surplus wealth for famine relief and advocate against cruelty to animals, he advocates euthanasia, abortion, and other practices when any killings would produce optimal utility.  Also, whether or not Singer advocates love will depend upon when love will produce optimal utility.
