In Western cultures the dominant group is still white AngloSaxon Protestant and Catholic, and to a lesser extent, white Atheist and Agnostic.
Therefore, members of any other religious/ethnic group may, at some time experience discrimination. Especially if your dress code, skin colour and language are different. Discrimination is also a risk factor anywhere, in immigration situations. Emigrants who do not get prior education about their new host country are at higher risk.
It is impossible for healthcare institutions to address the wishes of all ethic groups. Policies therefore are mostly generic reflecting by default host culture traditions.
