Encouraging sin is not love, read John 8. Jesus doesn't condemn the woman caught in adultery (a sexual sin just like homosexuality), but he tells her to leave her life of sin.
10 Jesus straightened up and asked her, “Woman, where are they? Has no one condemned you?”
11 “No one, sir,” she said.
“Then neither do I condemn you,” Jesus declared. “Go now and leave your life of sin.”
