It has been repeated many times, but the idea that cis het men would go to any bother whatsoever pretending to be trans women in order to sexually assault someone when they do so all the time already and are rarely and barely punished for it is patently absurd, and yet we are constantly forced to address this nonexistent, made-up problem by people who just want trans people to disappear and die.
Essentially, every anti-trans narrative and talking point is rooted in a hysterical overreaction to something transphobes made up themselves, which have no basis in reality, and which fall apart under any common sense examination, and yet it is trans people who are constantly accused of being deluded or in denial or out of touch with reality.

If you're concerned about cis teens transitioning by mistake, well, don't, it's vanishingly rare, and the solution isn't loading teens up with even more hang-ups and anxieties about their appearance, behavior, interests, and sexuality by straightjacketing them with "traditional" gender norms or hiding information from them or refusing them access to care, putting them through an ordeal just to obtain advice and answers to very basic questions.

Good decisions don't happen under duress.

If you're really, really worried about it then you should want the process to be as painless as possible, for there to be an abundance of information and counseling, and a lack of pressure to make decisions quickly because of limited time and access to care, taking full advantage of puberty blockers, and for young people to feel accepted no matter what path they take.

Frankly, it's none of your business anyway.

No one benefits from making this process fraught with stress, fear, and threats of violence, nor from denying people access to basic and often life-saving information, support, and care.

No one except fascists who hate trans people and want us to die and who not so coincidentally want to subjugate women and protect rapists and abusers from accountability.

You really have to be a sucker to fall for their scapegoating of trans people.

Trans people fundamentally tap into the two motivating factors on the right.
First, fear of people who are different.
Second, the assumption that success can only come at the expense of others.
These are the unspoken foundations of right wing thinking, and explains why they hate blacks, Jews, immigrants, gays, etc, etc.
