It is an interesting concept and thanks for putting it up here. I hadn’t heard it before.
I agree we should try to keep the discussion simple on the clobber passages. Paul says in many places the Old Testament law no longer applies. (eg All of Galatians, Acts 15, Rom 10:4, Phil 3:2 etc)
If anyone tries to claim that just because the topic is homosexuality, none of those verses apply (and most do), then Lev 19:37, Lev 20:22 and Gal 3:10, 5:3 says they MUST obey the WHOLE law. We get absolutely no choice about that.
When your children throw a tantrum and curse you or your wife, how many of them have you killed lately? Lev 20:9 says you must.
Lev 19:17 says “Do not hate your brother in your heart” I often ask people, thinking of your gay brothers and sisters in Christ, does that verse get a tick or a cross?
