Let us remember that our fight is with Satan, not the LGBTs . Those who are part of the LGBT movement are being deceived by Satan. Since marriage is a perfect picture of the Holy bond between God and His Church, Satan hates Holy matrimony and seeks to utterly destroy it.
But the truth is that God still loves each and every one of them, but He will not tolerate their sin. Let's be very careful that we as Christians show love to these people. And by "love", not condoning their sin, but admonishing (pointing out their sin) and ever reminding them that ONLY God can forgive (and remove from their lives) this sin through the saving Grace of Jesus Christ.
On our own, we cannot fight Satan and win. It is imperative that we turn to Christ to help us in this battle. It is essential that every time we have occasion to talk to, or talk about LGBT people, or to confront the movement, that we first pray and shield our words and deeds with the power of the Holy Spirit. I am by no means advocating just sitting back and only praying and depending on God to work..... but asking that God use us and our compassion for these sinners to battle Satan.
Ephesians 5; 6-11 We are to have no fellowship with the workers and advocates of darkness and evil but are rather to reprove, mark and avoid them. Enabling is partaking.
