I want to know the answer to the following question:
What did Jehovah's Witnesses persistent legal challenges result in, in the United States?
All the background I'm provided with is that "Among the rights strengthened by Witness court victories in the United States are the protection of religious conduct from federal and state interference, the right to abstain from patriotic rituals and military service, the right of patients to refuse medical treatment, and the right to engage in public discourse.". Is that enough to answer the question?
Answer: no
