I disagree. I think one of the overarching messages of the entire Bible is about God/Jesus loving someone even if - according to the Bible - they sin/live in sin. It's not an approach that's allowing one to hide hatred. God/Jesus approaches those in sin, recognizes the sin, yet still loves the person.
That's great and all, but it doesn't work for people who aren't God/Jesus. Our brains aren't wired to be able to love the sinner and hate the sin without great difficulty.
