This is so vague (and stupid), point out specific issues from in online and inperson radfem spaces. Radical feminism has plenty of differing perspectives. Also, with the phrase TERF people who aren't actually radfems are calling themselves so.
Personally keep thinking to what happened with Helena, a straight detrans woman (@lacroicsz on twitter). Recently, she made some tweets about race that were interpreted badly and "radfems" (some also detrans) on shittalked and then blocked her, calling her a tradwife, etc. Not saying she's a saint but it was really embarrassing to see.
