@piesforever I'll add my voice to this one as well.
I was a lurker on MN for a long time, reading things and building up my knowledge through listening to others. My entry point was gender dysphoria in adolescent, autistic girls but I realised that in order to understand this (and help my daughter with her confusion about what "gender" meant for her), I needed to widen my reach and get my head around all of it.
Despite my concerns for my daughter and others like her, I've remained "in the middle", similar to how many others have described.
I still use preferred pronouns in some contexts - never a child and never where the clarity of someone's sex is specifically important. In the former I'll just avoid any pronoun. In the latter I'll either do the same or, in some circumstances (probably on fewer than 5 occasions so far at a guess), I'll use sex-based pronouns.
I decided to join Twitter when the harms relating to children and gender identity belief started to bubble up in the public discourse a bit more. It's not fully open in discussion yet but it's getting there, with puberty blockers and the question about how teachers and schools should handle this whole topic.
In the past on MN, I've been questioned about whether my views are genuine and I've been told off several times for "policing people's language". I still maintain that I never did and that I was simply advocating for respectful debate but never mind that now 😁 The reason I mention it is because it hopefully illustrates how "in the middle" I've been and am. Even when advocating for respectful debate, I've also always seen value in different voices. Yes, that sounds a little like a paradox but we really do need all of it IMO. Some people's engagement styles have shifted over time from more "in the middle" to hard line, but from everything I've seen that doesn't stop people caring about trans people too.
But caring for others doesn't mean letting lines be crossed. Nobody should be able to identify their way across someone else's boundary. Not everyone believes that we have an inner gender identity, an innate essence of being male, female or other. Why should a believer get to force others to accept it as a truth?
From my experience on MN, that's what I see in other people who post: care for those who experience gender dysphoria but hard lines on what can't be forced on to others.
I'm on Twitter more than MN now, taking my "in the middle" style of engagement with me. Where there is substance to a comment, I'll engage. I've had some great discussions on that basis but most of the time, that involves me ignoring insults that are flung at me. I only comment back on the actual substance and if there's not any at all, I step away. Despite staying in the middle in my engagement style (I'll admit I'm prone to the odd bought of sarcasm, but mostly not) I've been called: Nazi, bigot, fascist, transphobe, deluded, part of a cult... and my personal favourite... A paedophile! That one was when I said that children should be allowed to go through puberty in relation to a conversation about the dangers of puberty blockers.
