RE: Although why anyone would want to publicly brag that he is an unrepentant sinner and a pervert, is beyond me.
Because he is not a Christian and does not believe that homosexuality is a sin or a perversion.
The “God” he refers to is not the God of the Bible.
True, but God has imprinted His Law on every man's heart. We are all made in His image. It takes a large, and deliberate act of rebellion to blatantly act against His Law. When people reach this level of depravity it is unfortunately a probable sign that God has given them up. Their consciences are seared and unfeeling.
