Stephen Whittle, you must realize you and your academic-friendly social bubble is not a good representative sample to answer the question? Honestly, I'm not sure the purpose of that other than to show what cozy cocoon you and yours have been able to make so you can ignore what's going on with the rest of us and that has nothing to do with being trans men or dysphoric. I think your bubble has left you out of a lot going on within our communities, many have and continue to live in the purge world, today is a very strange time too.
Those who 'go on the computer' more can see the various popular sites where the fetishization of the rape and forced pregnancy of trans men and other female dysphoric people on various popular sites. We can see the social media sites where when we speak up, we get told we're using our "masculine privilege" and threatened with violence, rape, and murder. We can see, regardless of dysphoria or how we identify, females are at a significantly higher risk of male violence than our male counterparts which is why many of us don't use male spaces even when they're "given to us" (which I find a highly debatable idea). That's why so many of us have fought for years for unisex single stall public facilities, we know that many of us are getting left out and still at risk.
The answers to where are all the trans men is not 'oh, all out doing suitably manly hobbies and skills around the house'. That is the most patronizing bullshit though there has been quite a bit to choose from. It's like saying the reason that there aren't more women publically praised for activism is that they're all knitting and cooking and just too tired for all that. We can't pretend that there are not systemic reasons both within wider society and within the current trans rights movement which, while trying to act revolutionary, does keep a lot of the same power hierarchies tightly in place, that has continued to ignore and silence the voices and contributions of so many female dysphoric people across all identities.
Just like the rest of society, most of us don't have naice careers but survival jobs if that, most are struggling, self medicating is a massive issue both on online bought hormones people are treating as their only hope to the pain alongside a fuckton of alcohol, drugs, and painkillers, actually face to face time with professionals is shrinking as are most services, so many are just trying to keep a roof let alone have a garden to do whatever in. The image painted in the OP I find is a bad if kind attempt to say we're just like everyone else, but forgets most aren't that well off and most activists do the daily stuff alongside jobs and all the other stuff...many just because it's needed to survive, to hope tomorrow might be better.
And really, I find the idea that in response to questioning and concerns about pregnancies on mixed sex trips for the GGA, you jumped to the GGA's contraception advice which is meant to be general sex ed and not for what to do on trips in their care and very much not an appropriate response to how to deal with the concerns about the inclusion of possibly dysphoric males. These are 11-15 year olds, these are all underage kids and the very least they deserve is safe sleeping spaces on trips. We're struggling to deal with sexual harassment and threats made by boys against girls as young as 7, the concerns here aren't how to be the liberal fun parent but how, during the very difficult time of puberty, to safeguard their comfort, safety, and access to public activities as much as possible. If my Bible Belt high school with very little notice could arrange policies, changing facilities and ensure sleeping space on trips so that one dysphoric student could fully take part in an optional sport simply because I wanted to, then people who actually know about dysphoria should be able to put far more effort and consideration into the situation than condoms and emergency contraception pills.
Considering that at least half of dysphoric people have a history as victims of sexual abuse, and the related correlations between that and high risk sexual behaviours & several mental health conditions, dysphoric kids are in need of seriously considered protections and safeguards that you're suggestions completely ignore along with basic human empathy and considerations others have brought up. Really, no matter what identity you've chosen to fight in, you should be able to manage some compassion for other dysphoric people that the response to how to deal with the risks for and from a dysphoric young person should not be centered on contraception.
Your entire tone lacks compassion and understanding and while I'm sure you have so much more useful things to be doing, maybe consider for a minute what the grumpy suicidal teenage you might have needed. How would that child like to sleep in a room with boys on a trip, even if they'd been given condoms? Would that really show the kind of safeguarding and understanding that child would benefit most from? Would you have felt safe and wish to partake in that? Can you understand why many other female teenagers, no matter how dysphoric or not, would not be comfortable with that?
Enjoy India. Hopefully, you'll listen more to them in their space than you have to many here. There have been some great writing by others here and it would be nice to see them well responded to but by your record so far elsewhere and here does not fill me with confidence. Hopefully, the trans men and other female dysphoric activists coming up now will soon be in stronger positions to speak for us because I think those who have gotten in with power have forgotten what's going on for the rest of us. I like to have hope, I think we all deserve better, we'll all see though.
