Not the same to me, no. It's okay if you don't like it though. It's a quick and easy way to identify that very real group of women hurting womens' rights by opening up female spaces to males with pleasure and enthusiasm. I wonder if you have a better term?

I never see radfems complain about the men who actually do bad things or men who enable other men.

I haven't seen the male equivalent of handmaidens. I say this as a hardcore feminist. It's a very specific thing btw, not a catch all term for "bad woman." The men do not let their spaces get taken over, they don't talk over other men to allow female people in their spaces. This problem doesn't exist much on their sides. All those trans threads get essentially shut down in the gay subs, they stick together and don't throw each other under the bus in the name of "progress" and politeness. The same cannot be said about the lesbian/women's subs. I mean compare r/actuallesbians with r/gaybros. They're both male subs, because the women couldn't keep their space (and willingly gave it away) and the men could (and did not willingly give it away.) It's an unfortunate trend that comes with being of the sex that is expected to put (men) before themselves, even at the expense of your sisters.
