Feminism is an ism, it is very good in itself. Now of course there are many opportunists hiding behind the label and doing really bad things. E.g., the self-proclaimed feminists/TERFs who are against trans rights, or, women's autonomy over their own body and mind.

And I am not making a generalized argument/ No true scotsman argument as you mentioned. I am just saying if anyone wants to dominate anyone or a collective of people, they are anything but feminists. It is you who are making the mistake and accepting those people as feminists, just because some of them are claiming to be.
