Surely you’re not saying that homosexuals can be Christian? They can CLAIM to be Christian but the Bible says unrepentant homosexuals will not inherit the kingdom of God, meaning they’re going to hell. That definitionally means they’re not Christian. The Book of Revelation reinforces this judgment.
"Woe to those who call evil good, and good evil; Who substitute darkness for light and light for darkness; Who substitute bitter for sweet and sweet for bitter! - Isaiah 5:20
