The new Ghostbusters movie has an all-female main cast (compared to the all-male main cast of the original two movies). That in itself isn't good or bad. However, there are many indications that the film makers are trying to pander to feminists and social justice warriors with this "girl power" casting. (Just make a google image search for "ghostbusters girl power" for one example of this.)
Is it working? Are feminists and social justice warriors happy?
Of course not. They are never happy. They cannot be happy. They are incapable of being happy. They are always angry. Nothing is ever good enough to them.
Of course they are whining and complaining about how the movie is "racist" and whatnot.
What exactly did you expect?
Capitulating to social justice warriors is useless. By trying to pander to them, you are only drawing their attention, and begging for their ire. It will bite you in the ass.
Stop capitulating to them. Stop pandering to them. It doesn't work. They will never be happy, and they will only attack you.
