Fortunately, not all the Irish are insane - just the government. Some are actively opposing this new law and the constitutional basis for it. Have a look at the Atheist Ireland website for more information, including their deliberate attempt to provoke a prosecution from the government.
You know, I really hate people telling me what I can't say - especially governments and religious nuts.
And, just in case you thought the people who introduced this new law were sincere, God-fearing fundamentalists, here's a quote from Micheal Martin, Irish Minister for Foreign Affairs, opposing attempts by Islamic States to make defamation of religion a crime at UN level, 2009:
“We believe that the concept of defamation of religion is not consistent with the promotion and protection of human rights. It can be used to justify arbitrary limitations on, or the denial of, freedom of expression. Indeed, Ireland considers that freedom of expression is a key and inherent element in the manifestation of freedom of thought and conscience and as such is complementary to freedom of religion or belief.”Governments and hypocrisy, eh? Who'd have thought?
