Protected by first amendment, you dont have to like it, but they can do what they want to it
Of course they can. Unfortunately, one of the things often lost when talking about "rights" is that while there are things you CAN do, there is a responsibility to NOT do certain things as well. And as people push those boundaries suddenly you have to deal with some transgender having the "right" to use the girl's locker room in high school. Sometimes, rights should be balanced with common sense.
