"- A Hassidic Jew demanded to a female police officer who just pulled him over, that he would not speak to a police officer unless he was a male.  The police officer was requested by her superior to obbey to this demand.

- A young Sikh demanded to bring is Kirpah (A ceremonial knife) into classrooms.  Court ruled the school had to let him bring his knife into class while other kids with skulls on their shirt were being kicked out

 - A jew community demanded the windows facing the street of the local YWCA to be tinted so they wouldn't see women training while walking in the streets.  Government accepted and paid for it.  The list goes on and on, I think there are 5 or 6 other cases like these ones."

"Would you also be in favour to train some extrem Christians to become doctors, even though they are against blood transfusions or medicine?
