Kudos for a thoughtful response to an inane comment.

To say 'Render unto Caesar what is Caesars' does not mean that Caesar was a good guy and we should support him. This is earth, not Heaven. Bad rulers and bad laws are numerous, but should not be obeyed if we can't get away with flouting them.

As the 1st commandment says, our allegiance is always and above all to God. No law of men changes that.
