I don't get why you'd ask this on Mumsnet, you know the answers you're going to get here!
Well there are a wide range of answers so stick that in your pipe and smoke it.
The whole Terfnet from outside makes me laugh when i regularly see on twitter things about "sucking my lady dick death to terfs" and when it is called out as misogynistic it is dismissed as only words. But we have all seen the "literal violence" references to being misgendered by accident.
So here's the thing. I'm not a Terf. I literally want the entire universe to live their best lives without harming others. I'm quite the fan of Jeremy Bentham also, so i also belive that if you can improve the lives, even marginally, of the majority, you should be doing that.
I also believe that a society can be judged on how it treats the weakest in that society and we should treat minorities with dignity and respect.
None of that is incompatible with being a staunch feminist, a trans ally and a supporter of women's rights (including their right to sex-based services where wanted/required)
my reading of MN has shown me that outside FWR any anti-trans posts are likely to be zapped. And even on FWR they are treading a fine line (that i have, as yet, failed to identify). I watch aghast as statistics are manipulated - and how the old adage of unifying against a common enemy (who is causing most of the VAWG and transwomen and transmen? who?) has fallen by the wayside in favour of groups of people shouting (on occasion vile slurs) against other groups of people.
But one thing that is guaranteed to make me roll my eyes. "what? we don't use pronouns to talk to the person when they are present" (assuming you mean 3rd person prononuns, because you almost certainly do use pronouns). It isn't about "PRONOUNS" it is about being open about your gender identity. And/or sex. And not everyone is comfortable doing that for various reasons that are not related to anyone else. That should also be respected.
