While outright bans on religious apparel are a serious limit on free speech and expression, those who support and wear religious clothing must also respect the rights of others to dress and live as they please, and should not be permitted to force their ideology or customs on others, even if they are family members. The problem with respecting the rights of religious individuals to practice their faith as they see fit while defending the rights of others to live free from religious compulsion is that there is no definitive legal standard by which the state can become involved to stop religious abuse.
Take for instance the ability of religious parents to not vaccinate their kids as other parents are required to do. According to the National Conference of State Legislatures, "all fifty states have legislation requiring specified vaccines for students... Almost all states, except Mississippi and West Virginia, grant religious exemptions for people who have religious beliefs against immunizations." Essentially, a religious parent can stop their child from receiving a necessary vaccination, thereby endangering their child's health, and that of fellow students. These exemptions create a special class of citizen that is exempt from laws based solely upon their religious belief.
