The ACLU is anti-religion. That is the topic.
actually they are not, if some people would do a little research and think for themselves they would realize that.
In February 1996, the ACLU filed suit in federal court in Alabama claiming two school districts engaged in unconstitutional religious practices. In October 1997, U.S. District Court Judge Ira DeMent issued a permanent injunction forbidding the DeKalb County schools from engaging in various religious activities. The injunction also ordered school officials to stop students from engaging in certain religious speech. The later part of the injunction went too far, a federal appeals court ruled in response to an ACLJ appeal.
One of the compromises that was suggested to the ACLU was the creation of a "free speech zone." This would be an area outside most government control where citizens could put up holiday displays of their own choosing. The ACLU was dead set against this idea. Their rationale? Citizens would use their free expression to support Christmas. The "defenders" of the Bill of Rights stood against free speech.
The American Civil Liberties Union of Oregon, which has long supported [the law that bans teachers from wearing religious garb], said the Legislature should not end it without enacting additional protections for Oregon students. The Oregon Education Association has not taken a position on the issue, a spokeswoman said.
So a student can wear an anti Islamic T-shirt but a teacher who is a Nun can't wear a habit or a Muslim teacher can't wear a headscarf or a Sikh a turban...that makes perfect sense.
