Because this might offend people!
Just kidding.
No way will the ACLU try to get those ads nixed. No way, no how. Too damn busy suing to have any and all public evidence of Christianity eliminated to worry about people publicly promoting atheism and offending persons of faith.
The cops? Too busy arresting Christians for simply standing around in public, particularly if there's an abortion clinic anywhere nearby, or a homosexual-themed event of some sort going on...
Atheists publicly promoting godlessness? So what? They're just exercising their rights, after all...
