I suspect you're right because autism seem to be seen as something cool amongst teens who spend all their time online but clinicians who work with people with autism are also reporting high levels of trans identification among their patients, largely teenage girls, who as we know are most susceptible to social contagion. Also, I don't know how it is in other countries but here in Australia there is assorted funding and assistance available to kids with autism that isn't available to others, so some parents are actually pushing to have their kids diagnosed, ridiculous as it sounds.
