I don't think we should remove everything pertaining to religion from the public eye. I also don't believe the public should be allowed to exclude other forms of religious thought at the same time. That's the problem we currently have. To many ppl think it's ok to put a couple of words in a pledge here; place a big couple ton ten commandments statue in a courthouse over there ect.. Yet those same ppl will fight tooth and nail if you try to add a jewish prayer to anything. They are also going nuts because some professor wants to teach a course on islamic religious beliefs. But its ok to teach about christian or catholic beliefs at that same college.
No matter how complex a lock may be. Someone will always find a key.
