It focuses on Section 1557 of the Affordable Care Act. Specifically, it ends discrimination based on gender and limits it to assigned/biological gender of male and female.
And you're like "what's the big deal? Why does this end healthcare for trans people?"
this is the part that's gonna bend your brain, and you'll have a hard time with it.
Let's say a trans man (was born with female factory equipment) gets ovarian cancer.
His health insurance can decline to cover any of the treatment. Doctors can refuse to treat him. Hospitals can refuse to admit them.
Let's say a trans woman is beaten by some random thugs. The ER doesn't have to admit her.
That has effectively ended healthcare in our for-profit healthcare system.
Because why would an insurance company pay for something when it doesn't have to?
