Well fortunately those aren't comparable to tourette's, since they're not illnesses.
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.
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.
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.
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.
