A word-sensitive thread block function sounds like a good idea across the whole site.
I don't understand why FWR has to have separate rules. Yes, some of the subjects discussed here may be upsetting for some MN users, but that's the same across many of the boards surely? Some posters are saying that they are interested in feminism but can't bear to look at the board because it's too distressing to see all the threads about trans issues, so those threads need to be safely locked away in their own enclave, out of public sight. How is that different from someone (for example) who is interested in Style and Beauty, loves fashion, enjoys make up etc but has alopecia and finds it upsetting to see all the threads about hair styles and products?
A broad-ranging site like this (and its broad range is inherent to its success as a community of - mostly - women) requires a degree of self-regulation from its users. As we're fond of saying, MN is not a hive mind. There are small communities within the larger one - dog lovers, knitters, runners, parents of teens/adults/children with SEN, and yes - women (again, mostly) with a keen interest in feminist discussion, analysis and activism. You find your tribe here, you don't barge into discussions on boards you don't like ('I'm terrified of dogs and they make me sneeze so stop going on about how good they are!' 'I rent my house and I'm not allowed to redecorate - can you please not discuss paint colours on Property&DIY?') or come along and demand that an existing tribe is broken up or censored to accommodate your sensitivities (and if you can't find your tribe, you move on to look for it in another online community.) That's why it seems crazy to me that external monitors are allowed to dictate what's discussed here, and why this latest idea to split the FWR board seems bonkers.
So (sorry for rant) an opt-out word search function seems like a good idea. But if the change does go ahead, I suspect I'll keep on posting on the Sex & Gender board, regardless (if that's what it's going to be called) and avoid the fun feminism, because I don't think that's really my tribe. I guess it'll be the ultimate poll to see if us mean old GC wimmin really are a 'vocal minority'.
