Sorry, but if you judge your society in light of your society you end up with no functioning reference standard at all, just a slippery slope.
It’s how the looney left of the 70s and 80s now dares call itself mainstream so that the only thing left of the old extreme left are the few proud Communist and other nutters.
What it means to be Man does not change.
Which is precisely why things said even thousands of years ago are often not only valid in their meaning but are frequently far more humane and true than any the post-modern slop shoveled out in schools these days.
That is why it is so important that a contrast be clearly noted and outlined, with no confusion. Recent events (very recent) in Brussels bear this out, where many would like to confuse 7th Century standards with 21st Century behavior.
