Your slippery slope argument is horse shit. Women wear "slut" as a badge of pride among themselves because men have been calling them sluts for ever. Blacks wear "nigger" as a badge of pride among themselves because whites have been calling them "nigger" forever.
Women are getting around to walking around with their shirts off and practicing sexual promiscuity, both things men have been encouraged to do forever. If this makes you angry, you need to realize that other people enjoying your privileges does not amount to you losing your privileges.
Moreover, if you're really upset by the lack of modesty in these women, then lead by example. Be modest. Raise modest children. That's the best you can do.
Maybe save up some money, by some property, and have a commune which enforces your values. The mormons have done this.
You cannot and will not revert society with your outrage at the ideas on display here, you can only inflame the minds of people who embrace this kind of sexual freedom into being even more outrageous. This is the principle behind all trolling.
I've been waiting years for white boys to catch onto this and start calling each other crackers in solidarity, but nope. Nothing. Just more puritanical outrage and pearl clutching while they pretend to be the ones who embrace the "rebellious" and "politically incorrect" ideals.
Transhumanism is going to render all these things irrelevant soon enough, and the rich and powerful will have their hands on that first.
Your first and foremost concern should be the fact that slavery is going to be reintroduced by the ruling class as they use technology and law to triple their lifespan and halve the lifespan of the poor while they escape from Earth and establish an interplanetary feudal hegemony.
You should be concerned that eight people control more wealth than the bottom half of the planet, and are using it to create circumstances which will leave your grandchildren in bondage.
But no, the scary sluts are really what's gonna destroy us all.
