Nobody asks them or tells them to be trans.
Alright, since I see so many of you republicans getting confused over trans identity and drawing the incorrect conclusion that trans identity is forced on young children, let me explain. For the sake of this explanation, I am going to assume you're a cisgender male. Suppose you were assigned female at birth. Going through life knowing that your body did not match your identity is extremely distressing. This condition is known as gender dysphoria and is a result of mismatched bodies and identities. Hormone replacement therapy and gender-affirming surgery has been scientifically proven to treat gender dysphoria. Since I'm guessing you're going to bring up de-transitioning, let me tell you a few things.
1. This isn't super common. 99% of people who go through gender affirming care do not decide to de-transition.
2. Of people who do de-transition, the most common reason is societal pressure.
3. Also, of people who de-transition, many choose to later re-transition.
