At the heart of this question, I would say, is what you believe about God. If you do believe in God, and that he is everlasting, omnipotent, omniscience, and is the end-all, be-all authority of the universe and everything in and out of it, then past, current, or future social norms should never be used as any kind of measuring stick. Nothing of man or of the world should be the measuring stick.
It is only His word and His opinion that ultimately matters, no matter how the current social climate may shift or change. And frankly, from taking a look around, while technology has advanced, mankind really hasn't. The same issues dealt with in the Bible thousands of years ago are still the same issues at the core of our world today. Clearly mankind hasn't figured things out for themselves.
2 Timothy 3:16 ESV -- All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,
Matthew 24:35 ESV -- Heaven and earth will pass away, but my words will not pass away
