He calls it the "female Ghostbusters" because that is what it is being called by various people on the internet, and he uses it as a way to show how calling it "Ghostbusters" without an additional qualifier was not a good idea because now people make up monikers to tell it apart from the 1984 movie.
If you made the effort you could easily have found out, either from reading the comments to the video, by looking at the video reactions or simply by looking at the suggested watching at the side bar, that there has been a LOT of negative feedback to this video along with reactions to that feedback. It's not my claim. It is easy to find out, it's not some obscure, arcane conspiracy that you have to unearth by digging through pages and pages of google results to carefully crafted search statements, it's plain to see if you wanted to. Since you don't like watching videos, I'll refrain from linking them, but allow me to say that much: It's not my claim. You'd just have to scroll down to the comments to the video.
I do not have to engage in "tricks" or try to deceive you, what I say is easy to show in the links provided and even easier to find for yourself if you wish to. Again, we're not talking about obscure webpages hidden somewhere in the dark web, that shit was all over YouTube and Twitter, people made comment videos to it, commented on the amount of hate it generated, etc. This is hardly difficult to find.
And yes, there were people who called him all sorts of things for just having this opinion. Take a few minutes to go through the comment section of the video and you'd be amazed.
