ACLU sues Catholic hospital for not preforming an elective hysterectomy on a transgender woman

The American Civil Liberties Union (ACLU) is filing a lawsuit against a Catholic Hospital because it refused to perform a transition surgery for a transgender woman. The ACLU suing a Catholic organization because of its beliefs is not surprising.
The ACLU filed a lawsuit on behalf of a 35-year-old woman (Ms. Minton) who is suing Mercy San Juan Medical Center, a Catholic hospital, for refusing to remove her vagina. The woman wanted to have the elective hysterectomy because she wanted to transition into becoming a man.

The hospital explained:

We understand how important this surgery is for transgender individuals, and were happy to provide Mr. Minton and his surgeon the use of another Dignity Health hospital for his surgery within a few days.

We do not provide elective sterilizations at Dignity Health’s Catholic facilities in accordance with the Ethical and Religious Directives for Catholic Health Care Services (ERDs) and the medical staff bylaws.

Ms. Minton (who prefers to be called Mr. Minton) was able to have the elective surgery at Dignity Health's Methodist hospital only days after the Catholic hospital's denial. So why is Ms. Minton bring this lawsuit if she was able to get what she wanted? She told the Sacramento Bee newspaper that "“No one should have to go through that."
