slut-shaming is the act of declaring someone a slut (or a whore or any other similar word, or even promiscuous, for that matter) based upon perceived sexual behavior: the clothing someone wears, the way they communicate with potential partners, the people they date, the number of partners they have (or havent) had, and the type of sex they enjoy.
These would all be acceptable ways of determining a woman’s morals. Society has always used shame to uphold community standards. It’s a good thing.
Shaming is the proper social response to the shameful.
Ridicule is the proper social response to the ridiculous.
