How about gay rapists? A close male relative of mine was raped by a gay man who used a sedative placed in a drink to knock the then 15 year old out. The boy woke up to being anally raped on a boat out on the water. I was a Christian, but I found the man and beat his head in with a fire extinguisher I happened to spot on the wall next to his work desk where I decided why hurt my hands when this metal will do nicely. I think I hated him pretty while I was doing it. Did I seek forgiveness afterward? You bet I did.
Are you saying you attacked him as you discovered the crime or later? I don’t think you hated him because he committed a terrible crime, not because he was gay. Also, are you saying you left Christianity because of this?
