There is a cultural conflict going on here which has less to do with race than it has to do with campaigning strategies.
I have used 'we' and 'us' here but this is just my personal impression of 'us' as a community (MN feminists/FWR/Sex & Gender topics) - others may disagree:
A lot of us here mistrust bald assertions of 'lived experience' because we have spent the past decade having men tell us, with menaces, that they have 'lived experience' of being a woman. Women here have been banned from platforms, lost their jobs, sometimes even been prosecuted for questioning the 'lived experience' of men who say they are women.
We ask for evidence because we are required to provide it. Fair enough, a lot of the things we are raising awareness of are so extreme that we would come across as insane if we produced no evidence (see the most recent example of the 'adult baby' man being allowed one-to-one access with children in special educational settings).
A big chunk of our activism has ended up being in litigation. Another big chunk has been giving evidence to inquiries, consultations, committees etc. or submitting FOIs and compiling reports. These strategies are proving highly effective (if slow) but they wouldn't work unless we had done the work of compiling copious amounts of evidence and being prepared to produce it. A huge amount of work goes on on FWR collecting and collating evidence. That's one of its greatest strengths.
Also we ask for evidence because we are constantly presented with claims, some of them extremely dangerous, that do not hold up to scrutiny.
'Trans kids will kill themselves unless their identity is affirmed'
'Puberty blockers are completely reversible'
'Trans women are no more violent than other women'
Also we ask for evidence to highlight dangerous claims that can have no evidence.
'Trans women are women'
'Men can give birth'
'Lesbians can have penises'
These are the kind of claims we are told we must not question because that would negate people's 'lived experience'. We are told that if we do not agree with these statements then we are denying trans people's right to exist. We are accused of genocide.
So it's fair to say that MN feminists, especially on FWR/S&G, are pretty keen on evidence and suspicious of claims of 'lived experience' which are not backed by any evidence.
We care about details and concrete examples because we are practical activists. We don't just want to know how awful things are, we want to know what we can do about it and the best way of doing that is to work out exactly what has gone wrong and how to put it right.
So for example, the way to remedy the racial disparity in maternity outcomes might not be to just shake our heads and bemoan systemic racism in the NHS but to work out exactly what has gone wrong for each woman and baby and collate and analyse those results to come up with practical, concrete recommendations, whether that's something highly contentious like rethinking the most punitive aspects of immigration policies, or mundane technical things like reassessing APGAR scoring or recalibrating oxymeters. It will be all of these and more and the only way of finding this out is to dig into the details.
Of course there will always still be racists, just as there will always still be misogynists. The trick is to route around them and address systemic dysfunction at the systemic level. Get the right laws, policies and guidance in place and insist they are adhered to and who cares what ugly thoughts someone has in their individual head? None of us can police that anyway, not even if we send them on a course.
My impression is that anti-racist campaigners on MN do not use these same strategies, that they view assertions of 'lived experience' as the most important kind of evidence and view requests for more concrete evidence as suspicious. I am unclear as to the exact aims of this movement beyond the generic 'end racism' or what the roadmap is of how to get there.
I will fight against systemic racism in any practical way I can but I will not waste a single second agonising over my supposed 'white fragility'. Neither will I automatically believe without evidence what anyone says about their 'lived experience' regardless of race or sex or any other characteristic.
