So, they aren’t all different either.
The problem is definitional. I generally don’t define the ones I agree with as feminist. I define them as normal people. It’s the ideologies I don’t agree with that I call feminist.
I once met a lady who told me she was feminist. So I asked, in what way? She says, like I believe in equal pay for women. I said, so does everyone–that’s just normal. (FTR: there is equal pay)
