Seems to me that if you have to pass such legislation, in a state as politically conservative as Idaho no less, you’re admitting that your government universities have already developed an institutional culture that fundamentally restricts and threatens religious freedom and religious expression. Such culture, promoted and protected by overwhelmingly a- and anti-religious faculty and administrators, won’t and can’t be changed by legislation.
