Atheists like this Kahle fellow run around, allegedly full of principles, but with no ultimate source for them. I mean rally, what grounds does this guy have that there should be no crosses on public land? His own opinion? That is all atheists have in the end, and therefore they are never consistent.

Just because one is an atheist, it does not mean that one does not have a source for one's principles. One's principles can be drawn from science and the physical universe; they do not need to be drawn from supranatural sources.

However, as you say, there is no legitimate reason for taking crosses, which do no harm to anyone.
