Why are people so against the "Pro-hoe" movement?

I always see women constantly throwing terms around like "whore", "slut", "thot" to describe sexually liberated women. Or when someone wears revealing clothing, posts their nudes (i.e, Amber rose), or does a profession like stripping they are regarded as nothing but a "dumb whore." Why is the naked human body shamed when someone is proud of their own unique body? And also, your sexual decisions are your own to live with. It doesn't matter if you have sex with ten men over a span of time or ten men at once. It doesn't matter how long you wait to have sex. It also doesn't matter if you don't want to have sex. I just want to know, why are women called "hoes" by other women for loving sex?
