I have no idea but like the attempt. My two cents (which is just a guess)...
To truly make this happen, the first thing to research is who actually controls the DSM. Who controls what gets included? What power dynamics are at play. Find out who, specifically, needs to be pushed on. And then focuses the pushing efforts that direction.
From there, can take a look at whether an online petition is something that would matter to these individuals. Surely can't hurt. But some petitions seem to do nothing. Then again, I mean, who knows. What goes viral and what doesn't a very complex thing.
I'm kind of weird though. I'm an idealist who also hates false hope and rallies against hope quite often because of it, while also thinking that many things are possible if approached the right way.
