Since atheists preach "Keep your religion private", and that is not what religions teach religious, should we force atheists to keep silent.?

..in public to stop them from being hypocrites for their religion of atheism?
Update: For example, having them banned from Y!A, a public forum where atheists preach their delusion?
Update 2: For the people who have difficulty understanding the question, this isn't about the definition of atheism, but atheists who preach preach "Keep your religion private", thank you.
