The ACLU is for a concept called "separation of chrch and state," the premise of which is found nowhere in the constitution. Oddly enough this appears to be defined as separation of the christian religion from all aspects of public existance in America. You are correct that the ACLU does not seem to make cases against Judaism for public displays of the Minora, nor against atheists for the procelytation of their religion. In fact it could almost be argued that the ACLU is for the establishment of atheism as the religion of America.
The ACLU has pushed the minority views of teh majority for quite some time now and I think that the majority is beginning to get sick of this political correct nonsense now that it is going to the extremes of renaming holidays and discriminating against the free exercise of religion granted us in America.
In my simple brains estimation, a kid that prays of over lunch or prays before taking a test while at a school should not be pushined nor should the school be enforcing arbitrary regulations for fear that the actions of such students might offend another child or their family. If my beliefs offend you then deal with it, thats life, but do not seek to cram your beliefs down my throat or cry to Big Brother to "fix or somefink." The problem doesn't lie with my prayer before lunch, it lies with your hatred for what that prayer represents.
