Who on this thread is "speaking down to people" - meaning, I suspect, you? You've made sweeping statements that portray untold numbers of "lib fem and rad fem groups" which include vast quantities of women of various races, ethnicities, nationalities, ages, disabilities and disease status as made up entirely of white women who are all racist against black women and ableist as well.

Challenging you on your statements is not "speaking down" to you. It's treating you as the intelligent adult who can show evidence for your claims that I/we assume you are.

You slagged off generations of women in your initial posts, but in subsequent posts you've admitted

I’m mainly talking about online groups such as r/gc

And

I’m very new to radical feminism as it wasn’t something on my radar a year ago.

So why not simply preface your remarks by saying, "I'm very new to radical feminism and my only impression of it comes from online groups such as r/gc which I only became aware of less than a year ago but which from my very brief exposure I got the sense that they are/were dominated by white women who are racist and ableist"?

There's no harm in being new to a scene. But it takes some gall for a newbie/rube of any scene to rock up to a scene forum and slag off most/all of the people who've long been in that scene based on the perhaps inaccurate and unfair impressions that the newbie obtained from very brief exposure to parts of said scene.
