It’s totally disingenuous to suggest that all the feminism boards are lacking is someone willing to make a coherent argument in support of trans rights.
For one thing, in that forum you will usually be one voice agains tens and tens of posters all aggressively firing back. It’s impossible to address every argument and comment unless debating on MN is your full time job.
For another, you simply can’t have a debate when the fundamental premise is something your opponent won’t even consider. If I say ‘gender and sex are not the same thing and don’t necessarily correspond’ and a poster responds to say that the only definition of woman they will accept is biologically female, where do you go from there? I can link (and have linked) to academic papers, essays and articles from psychiatrists and doctors and biologists all supporting the idea that gender and sex are distinct, but if all of that is irrelevant to a person who won’t deviate from their belief that there is only sex, you can’t go any further.
Anti-trans posters on the feminism boards aren’t looking to be convinced. If they were, they could do any amount of research and discover these articles and papers for themselves. But what they actually want is to share their view about transgenderism and have a crowd of others agree with them and tell them how right they are, and how wrong any other view is.
If someone like me comes along and says ‘please just consider this research, or think about this possibility’ I’m not going to be met with enquiring minds interested in a proper debate. I know this because I’ve done this, and what I got in return was accusations of being a ‘handmaiden’, of being so desperate to please men I would actively try to hurt women, of being naive and silly and immature, of being a lipstick feminist, of being thick beyond belief or powerfully deluded. A torrent of abuse, much of it sexist and ableist in nature.
I am very, very done with that topic.
