So....
The term Transphobic is a misnomer, and nothing more than a weaponised term to shame anyone who disagrees with trans ideology. It's a political term, and not the only term that's weaponised to shame people into not expressing their views.
Gender Dysphoria is indeed something that can lead to suicide in many cases, but that's not the whole story. You have to look at underlying psychopathology to get a clearer picture of what Gender Dysphoria is, and where it comes from. The irony in all of this is that the attempt to browbeat the general public into agreeing that gender can cover everything from pixies to Morris Dancing gerbils has actually caused a greater sense of difference, and therefore an increased level of risk in people who are Dysphoric.
There are correlations between personality-based difficulties and autism in GD, not always, but it's there. There's evidence that children who are Dysphhoric grow out of it and eventually live quite happily as their sex at birth. There's evidence that some people who fully transition regret it, and seek out a reversal of the transition, and there is evidence that people who regret transitioning are also at high risk of self-harm.
There are some real shysters out there, peddling their self led research PROVING that their trans ideology is spot on and that TERFS, Cis gendered infidels, and so on, deserve to die (yeah, anyone seen the Twitter comments aimed at JK Rowling by Trans Activists? bleeping disgusting, and those people would be taken to court, and prosecuted if it were up to me). Thousands of confused, vulnerable people trawl the internet every minute of the day, looking for an identity, something that fits, a place to belong, and lo and behold, there's the equivalent of the Jesus Army/Born Again Christians/Any other Cult organisation online saying "you belong with us-we can make you better".
There is evidence that "reputable clinics" are coercing children and parents to consent to giving the child puberty blockers. and there are now private and anonymised chat rooms where gender curious kids can go and talk to a "mentor" who will essentially convince the child they are trans, and will force them down that road to getting something they might not necessarily want.
Let's be balanced though, and acknowledge that some people transition and feel completely happy. Like a well-done nose job, they believe it's given them the appearance they need to feel they can function.
I would never ever want to see trans people who genuinely want to make a 100% informed decision to transition. It should be their right, and they should be guided towards the services that would help them do that. What I do want to see however is the ceasing of trying to invent an ideology that fits an agenda, and then purport it to be science. I have more than enough knowledge of science and research methods to know that I could provide a prima facie slam dunk that we are all descendants of Cumquats, and that our internal organs should be referred to as "segments", but it doesn't make it so.
The solution is to encourage people to accept their difference, to own their Dysphoria, understand where it comes from, and to develop skills which will allow them to navigate the world safely. Trying to pathologise and normalise something that is borne from a dysfunctional view of self, will do absolutely nothing to help that person feel ok about themselves. They can still refer to themselves as trans, they can still live as the opposite sex, but for duck's sake, stop those people who believe that anyone opposing their ideology should have their face ripped off by dogs and their children killed, from having any voice at all. Ever.
