This is not a fair argument. The problem is not with religion as a whole, it is that the religion being talked about or being displayed is a very thin slice of what religion is. The is the very definition of respecting an establishment of religion. If you value the constitution that display must go. Now if you wanted to have a weekly prayer choosing a different religion each week that would satisfy me, even as a rabid atheist. I doubt in the situations you are complaining about you would accept that.
