Don't call me a hypocrit for that. I don't think that any religious simbols should be displayed in such a manner that is representative of the school. Christian, Islam, Jewish, or any other kind. (Unless it's the artwork of another student, in which case it is not considered part of the administration or faculty itself).
If the law you refer to makes such discriminations as the one you mentioned, then it is wrong. It should apply to all religious symbols, Christian or not.
