What your thoughts on people who slut shame women but not men?

Because just about a century ago it was pretty much the norm for men to have a wife and a mistress, and both women were expected to just sit back and take it. But if a woman was caught cheating, it would scandalize the social register, since it was still a “man’s world”. Back then, women were actually considered “hysterical” if they admitted to enjoying sex, since it was thought they had no interest in it beyond wanting to get pregnant.
