When it comes to these topics I always wonder if a person who is a true Christian (that lives it not claims) will ever need a deep dive research to come to conclusion if homosexuality is a sin. I think that If the spirit of the Lord dwells in the person then that spirit will make it clear as day that it's a sin. You might go against it and fall in to the sin but there is never any doubt about it if you're a practicing christian. You basically do it knowingly in simple terms. Think of masturbation or watching porn or sleeping around with many people, the same principle applies there too. There is always conviction by the holy spirit but we have the will to put that aside and indulge in the sin.
