I’m with you—I have no idea what makes a person homosexual……..
It’s actually very easy to answer. We just need to look at the Bible - it IS sin. I suspect that Walker, being the son of a Baptist minister knows darn well the answer to this - he just doesn’t want to ruffle feathers. Gluttony is also pointed out in the Bible as a sin, as is adultery, drunkenness, lying, etc.
