Nah, "rape culture" had been a thing since the 70s when Feminists first started writing about it. It escaped containment to talk about the problem with prison (aka about men in a real sense) and then got taken back over by internet feminists in the early 00s.

By the time of GG it had actually fallen out of favor, along with a lot of more radical Tumblr Feminism in exchange for Intersectional Language.
