Love and truth
To me, the issue is very simple if you're a Christian. The Bible makes it clear that homosexuality is a sin. However, we can not forget that love is the key. Love is always the key. In the Bible it says Christians should speak in love and truth. Meaning regardless of the sin, whether it's sex outside the marriage, homosexuality, unforgiveness..., we should love the person but not accept the sin. Unfornuately, many times Christians have forgoten either the love or the truth. We need both.
