That's sort of an arbitrary distinction. Both are abnormal presentations that cause significant problems in day-to-day life and consequently have clinics set up to treat the issue. Whether the issue is voluntary for a particular patient is also similarly important in assessing an appropriate treatment modality.
Putting the obvious political agenda aside, I would argue teenage girls faking tourettes is pretty much the same phenomenon as teenage girls faking gender dysphoria. It's not helpful to pretend that faking tragic mental conditions isn't a phenomenon among teenagers.
"Both are abnormal presentations that cause significant problems in day-to-day life"
The same was one-hundred percent true about homosexuality for nearly all of human history in most societies. If the "day-to-day problems" are because other people are mindlessly hateful and intolerant, who exactly has the mental health issue? In terms of homosexuality, we now largely agree it is the bigots, not the queers, who have the problem.
Many groups are social pariahs, none have a suicide rate close to the transgender community. Dysphoria by itself is clearly horrible to deal with, that's why people are willing to have double mastectomies in the pursuit of easing their mental pain. A vaginoplasty is incredibly invasive and isn't going to have a meaningful impact on day-to-day social judgement. I really don't buy the claim that it's purely or even primarily about acceptance.
I would also point out that the the trans community themselves are advocating for greater access to treatment, not less. It's really not the same as the gay rights movement. Unlike gay people, treatment is literally one of their objectives.
Gender dysphoria is feeling uncomfortable in your gender-at-birth. Therefore, transitioning or rejecting the concept of the gender isn't the disease — it's a cure for the disease.
Again, the dysphoria is caused by not feeling comfortable with your gender. Trans people solve that by transitioning. That's why you don't see trans people regretting it or trying to undo it in any significant amount. Once they've transitioned, they feel comfortable with their gender, therefore problem solved.
Of course, that transition also usually leads to other types of discomforts caused by other people not respecting their decision, but hey, it's not trans people's fault other people are dickheads.
It could just be the uncanny valley. Like it or not, we’re used to looking at other people as being either male or female and many trans people don’t make good versions of what they wish to present as. There’s also some men who enjoy presenting as female as a sexual fetish which can cause problems in locker rooms and other female only spaces.
Oh I don't mean transition as in sex-reassignment-surgery-exclusively. Sometimes it's as simple as changing clothes and growing/cutting/painting your nails and hair.
