hate the sin, love the sinner

[Jesster]

A good example is loving someone with an addiction.

You can love the individual and try and help them step through recovery, and still hate the sin.

This separation of the individual from the sin, can be applied to any sin.

But what about 'sins' that aren't a matter of choice or effort on the sinner's part? Like being homosexual or not believing in god?

Well duh. You stone them to death to show them how much you love them.
