On The Claim That Societal Morality Is On A "Downward Trend"

One person commented, in response to a question of whether societal moral values today are less than in times past:

"Premarital sex. Children born to unwed mothers. Number of fathers who do not support their offspring. I'd say there has been a downward trend."

To which I responded:

These evils pale in comparison to the evils of the past like slavery, tyranny, and oppression. I marvel at how consensual sexual sin consistently ranks at or near the top of the list of evils perceived by doomsday TBMs who seem to think practically the whole world (except for themselves) is going to hell in a handbasket.
