freedom of 'no' religion?

lately I've heard a lot of lawsuits and issues that come up about the freedom of religion and how the atheists are getting their way about dominating the race. My mom's views are simple: "If you are an atheist and you value nothing in religious symbols or artifacts then why should it bother you so much?" Someone complained to a Costco employee that they didn't want to hear Christmas music. And now I watched a news story about the atheist organization in my state making a protest and not participate in the silence of prayer. Good then, if you don't believe in a God then the more power to yourself but you don't have to make a big deal about it. This country was found on basic rights and the freedom of religion is one of them.
