The current wave of exposing well known men for rape and sexual harassment will not stop them. Purges at the top don't change grass roots behavior. What we are seeing is the utter failure of what was called the New Morality from the rebellious 1960's. That was the abandonment of chastity and virginity until marriage.
You want to stop sexual harassment? Return to what worked better than what we have today. Restore virginity as a virtue. Sexual chastity protected women but for around 50 years that's been regarded as a joke. Our hookup culture is destroying us by more divorce and STD's. In breeds no commitment. No wonder we've had a divorce rate near 50% for years. When I was born it was about 5%. Yeah, 5%.
Go back, women AND men, to dressing modestly. Let's be honest and realistic. Men are more visually motivated than women. Ditch the low necklines and high hemlines for clothing that covers more. After all, women, it's what's on the inside of the woman that counts more, right? Modest clothing discourages lust. You see less, you lust less. And men, time to cover yourselves up too ... we're tired of seeing your rear end hanging out of those jeans when you bend over!
If we're serious about returning to chastity, then it's also time to clean up movies, TV, music and other powerful influences. You can still find other forms of entertainment that are uplifting and engender respect between the genders.
God's laws protect. He demands chastity. Hebrews 13:4 -- "Marriage is to be held in honor among all, and the marriage bed is to be undefiled; for fornicators and adulterers God will judge." Return to chastity and you'll have more respect between the sexes, much less rape, much less STD's, and less divorce. Unless you deal with sexual harassment on the grass roots level you will never get rid of it.
