Sorry this got missed and I confess I've only skimmed it. (It would be easier if the link were clickable).
My initial thoughts are - I see lots of feminist stuff on-line from young women (pictured with slogans etc as in the illustration on the article). It's great that they get it. It doesn't seem to be making much of a difference, though. Are their male peers changing anything at all in terms of their perceptions?
And I'm 
about the Fourth Wave definition. I really hope that's not where we're at. Because we really are limestone, then.
Yes, we still need feminism. Stuff that challenges, though, not just celebrates.
