except i'm not talking about the law, i'm talking about being civil.
there is no law against burning any book in america, yet it would be extremely rude to burn a hindu/muslim/taoist text in front of their faces, or stand outside of their religious buildings (churches/mosques/etc) and say that what they believe in is wrong.
i'm not sure why you are talking about prosecution and the ACLU. you're not going to get "prosecuted" after doing a thing like that. most likely you are going to get severely injured.
i don't think i have to tell anyone, that people often take their religion very seriously. even an atheist knows that.
