I have to point something out to you, as you have fundamentally missed a point.
No one has ever asked you to seriously push for destigmatization or make arguments to that effect. Arguing for it even has pushed Prostasia into disrepute and alienated supporters. I have serious doubts about whether it has made a difference at all, compared to random people arguing on Twitter, or mental health experts writing a letter. There is a big difference between saying something semi-publically on a forum and shouting into the open that destigmatization (nebulous term) needs to happen. Do you think a libertarian or someone who just wants drawings not to be banned cares?
No one has ever asked you to talk to controversial figures or about controversial treatments. It doesn’t make the slightest difference to the bulk of Prostasia’s supporters (they don’t want to read about these things at all because it is not relevant to them), and it outrages others. The main reason you have done so is at the behest of special interest groups within the foundation who wanted to get their viewpoints advanced. Guess what, had you asked more stakeholders, you wouldn’t have embarassed yourself.
Unfortunately, you have painted yourself into a corner, where your supporters are not actually the ones you wanted, but the ones you ended up getting. You fashioned yourself as a child protection agency, but you actually became the lolicon defense front. You also do not recognize the principle of restraint.
Once again, I personally think it is better to push for more punitive punishments, to lock someone up in a mental hospital until they’re mentally fit to enter society (if they’re actually insane and likely to go attack someone), or to execute them, than to pointlessly make people suffer to push a faux progressive agenda (and it won’t actually handle their problem of being insane). It is fine to say a serial child rapist + killer should be executed, although we have to recognize they may be killing them to stop them testifying against them. I also happen to be a proponent of euthanasia, which shouldn’t come as a surprise for people who have lost their four limbs and are effectively finished.
As for someone being uncomfortable for a bit until they get better (which is the real problem, rather than someone actually offending). Well, that’s life. They’re going to have to get used to their problems sooner or later and hiding them away (and replacing them with a new ones, at best) is only teaching them to avoid problems, rather than solving them. Good therapists even recognize this.
Vice media smeared a therapist who would rather take the road of solving a problem, rather than following the world of Hollywood therapy, which most often will make someone suffer and give them false hope. Good people get shat on by people who only care about more academic fame and a journalist who wants to publish a piece of clickbait. What this actually does it make the media outlet (and associated scientists) look out-of-touch to anyone who might want therapy and dissuade 95% of them from getting it as it clearly does not fit their needs (or concerns they actually have). Someone who had their parents force them into therapy was screaming and begging as if they would be killed prior to it.
What I have personally argued, and which is less relevant here (ignore it if you so wish it), is that violent crimes should not be treated the same as non-violent ones, direct treated the same as indirect, and to weigh the cost of locking someone up against not doing so, but this isn’t even necessarily relevant to you. We live in an absurd world where viewing images which if you argue harms someone (by virtue of it’s existence) does so at a far smaller proportion than someone directly molesting someone, but that carries the longer sentence.
It is disappointing prevention initiatives in schools or the community get little to no attention, because it makes the government look busy to pretend to be little girls online (at great expense to catch a tiny fraction of brain damaged criminals), or to rack up convictions for the sake of having more convictions. All in all, the priorities are fucked up. Society can visit what to do with lesser crimes, when it figures out what to do about the serious ones, and the vast majority of it rather than what appears on TCAP.
