The punishments mentioned in the Bible no longer apply.
I'd go further and say: The Bible does no longer apply.
So we shouldn't love each other anymore?
What has the Bible to do with that ? People loved each other too before the Bible was written. People killed each other off by significant numbers because of what the bible said. So, the bible is a potentially dangerous literature to me. Therefore you should treat the Bible just as an ancient book no different to any other book and don't focus your life and political leanings on it - because you could turn into a crazy that acts on what is written into an old book.
Matthew 22:36-40. Love is the greatest commandment, and you are saying love is invalid.
