Idolatry

As a person without religion, I never understand the logic behind the claim of religious prosecution made by dominant religions. They want a Bible, a Cross, or a verse of the Koran everywhere, and when it is illegal, they claim that they are being prosecuted. But for an atheist, the absence of religious symbols is their symbol. To put religious symbols anywhere is, by the definition of the religious, an affront and a prosecution of the atheist. Come to think of it, is it not an affront to the truly religious? Both Christianity and Muslim are against idolatry and the fetishization of religious symbol not a move towards idolatry? And to put things everywhere to mark their territories something that dogs and wolves do? Their desire to see their symbols seems to veer towards blaspheme.
