I think a big disconnect that causes all these dumbass infighting arguments is that a whole lot of people with a whole lot of free time don't really understand or internalize the phrase "death before detransition" and that a lot of us actually do the things we say.
People talking about DIY aren't doing it to mislead people. There isn't a shadowy cabal of dastardly transfems trying to get transmascs to OD on testosterone, which is less likely to happen than smoking a fat Weed Bunt and melting your brain because it is basically impossible in any practical way. No one's out here telling people they can DIY without knowing the resources for it. No one wakes up one day and decides, "lol gonna do some crimes because I feel like it!"
People who DIY do so because that is their best and often only option. By and large, people who DIY do not do so flippantly and do not find the nearest canister of Drugs and mainline that shit with reckless abandon. They don't order $1000 of hormones off the dark web and start shoveling as much of them as they can into their bodies without considering dosage and safety.
The fear of these imagined scenarios is 100% a concocted myth. It's born out of anti-drug and anti-trans propaganda and bigotry. Further fearmongering and Just Asking Questions helps no one and hurts the most vulnerable. Doubly so for the people who somehow see people forgoing legal (for now) routes of transition access for gray and black market alternatives and somehow manage to logic themselves into believing that those people are privileged, all while simultaneously acknowledging (or, more accurately, threatening) that they're evil criminals who can go to jail forever.
When these people, be they medical professionals or dipshits on the internet looking for someone to attack, tell people to just wait and to only use legal avenues, they're telling them to die. I began this with the phrase "death before detransition" because it is real. It is how many of us live our lives. DIY is not a luxury, just like legally-obtained hormones are not a luxury. These are what allow us to live. Without them, we will die.
Like the decision to DIY, this is not a flippant decision or something done out of spite. No one wakes up one day and decides they're going to kill themselves because they're too impatient to wait for something. Dysphoria and bigotry are not a non-issue or not so bad. For many of us, these things will and do kill us. Without the tools to overcome them, we will, without exaggeration, die.
And whether or not these people don't understand the breadth and scope of these issues or are just pretending to be stupid for the sake of bullying people, what they're doing is actively harmful to people and community. Seeding mistrust against the resources and channels that are the only lifeline for many of us kills people. Spreading lies about the risks of transition kills people. As much as I know these are niche issues brought up by a relatively small group of losers online, it doesn't change the fact that there's the potential for real, material harm here.
In my view, there's no difference between an NHS doctor putting someone on a waiting list for years with no end in sight and a person lying through their teeth about how buying Brazilian catgirl estradiol might be full of fentanyl or that the government is going to come busting down your door because you have a pack of pills. Both of these, whether or not the person doing them intends it, will kill people. These aren't abstract situations to just "discourse" about online - they kill people.
There's never a good time for this sort of bullshit, but it's especially bad in a time when the state is actively working on a genocide campaign, a major part of which is removing any and all legal institutional avenues for transition. If you're someone who goes around lying about and fearmonger and attacking people over things like DIY HRT, you're helping with that campaign. You're an active part of eroding the safety networks and lifelines that we'll need to survive this. You need to stop.
And if you're someone who's just mad because you feel left out because someone said people can do DIY and it sounds like they think you're not cool or edgy enough to hang with them or they didn't explicitly name or consider every possible situation in which something may not be wholly applicable, maybe just fuck off and mind your own business? Not everything's about you.
