Is this a reasonable position for Atheists or Secularists to take? Atheists have often argued that the Christian slogan to “hate the sin, but love the sinner” is tantamount to their claim to oppose religion but love religious people. However, I think this would not sit well with me (and many people of faith) because we DEFINE ourselves by our faith, whereas sinners do not define themselves by their sin.
Actually, I can think of only one type of sinner that defines themselves by their sin, being homosexuals. So to hate their sin is (to them) equivalent to hating them, the same way Christians feel an attack on their Christian liberties is an attack on them as individuals (as citizens and as humans).
Can you think of other sinners that define themselves by their sin? Maybe Nazis or the KKK, who define themselves by their hatred and superior feelings against people of colour. If we hate their sin, can we claim to still love them?
