It’s pretty clear that @Socrateswasrightaboutvoting meant that they felt (or others felt) that they had been attacked/ridiculed for saying "x is being racist" with other FWR posters saying "don’t be ridiculous x isn’t being racist".
Perhaps such an exchange did happen. But, it’s hard to revisit or re evaluate this argument without an example or context provided.
Going by this thread, the one example raised so far appears to be that characterising surrogacy as ‘selling’ babies is appropriation and, as such, is racist, but I’m not even sure that’s an example of what @ReleasetheCrackHen or @Socrateswasrightaboutvoting are talking about without further confirmation.
There does seems to be a lot of miscommunication on this thread. @ReleasetheCrackHen asked So, why have I touched a nerve in you particularly?
The accusation (as per the OP) that MN needs a closer watch of FWR in particular is the nerve touched. There have been many many attempts to silence women on that board by TRAs. The OP made absolutely no mention of any other boards. Why is that?
Then subsequent accusations of racism on FWR but without specific examples, and making no other accusations against any other boards, leads people to wonder if accusations of racism is another attempt to shut the board down. The one example provided of FWR racism was posters ‘being angry’ at (an apparently) black poster explaining the wiki editing process and contributing to this poster being ‘hounded’ off MN. However, when I looked at that original thread, there were only comments thanking that poster.
Evidence is very important. Both for confirmation of accusations being made, as well as facilitating learning.
