Kerdy, while this case isn't the US, the rights of a person apply even in private institutions. If I go to a private school here in the US, I retain every single right within the bill of rights.
Your attitude towards this could also be used to defend the segregation and prejudice against blacks.
Based on the logic you exhibit here, you could also say that if blacks want to be treated equally with others and even be able to use the same restrooms and drinking fountains as others, they should attend a public school or a private school that allows them to.
Human rights don't work like that. Human rights are universal, and it doesn't matter if you're in a private or public institution.
And that's the thing, her rights were not violated. Just like a military members right to freedom of speech isn't violated when joining the armed forces, because it’s a voluntary action with known expectations. Even better, a male Muslim, or Orthodox for that matter, can’t grow a beard for religious reasons. They know this prior to joining and accept these restrictions upon joining. Can I join a Quaker or Amish community and expect them to allow me to do what I want? Can I go to a Protestant university which requires men to wear a tie and show up in a T-shirt and expect no reply from the school? If I'm Native American and the school rule is no smoking on campus, but I claim its religious, should they make exception? No. This whole way of thinking is incorrect. She can wear whatever she wants, off school property. No rights violation, anywhere.
And to address you silly racial attempt, are there not black organizations which allow no one else to join? Indeed. Are my rights violated? Nope.
There are all male and all female schools as well? No rights violations.
There are religious organizations which allow no one but that religion, no rights violation.
My advice is to stop always thinking as a victim. Life is too short to consider one’s self a victim every day for every reason known to man. One persons perceived rights at the costs of another's actual rights is not how things should work.
I really need to stop posting from my phone so I don’t have to go back and change so much.
