Better be careful what you say about religion in Ireland. That you might insult someone is the least of your worries. You could get fined, assuming that a judge actually upholds this ridiculous (and ridiculously vague) law. The U.K. Guardian reports:
[The new law,] which was passed in July, means that blasphemy in Ireland is now a crime punishable with a fine of up to €25,000 (£22,000). It defines blasphemy as “publishing or uttering matter that is grossly abusive or insulting in relation to matters sacred by any religion, thereby intentionally causing outrage among a substantial number of adherents of that religion, with some defences permitted”.
I wonder if I could be fined in Ireland for insulting the most powerful American God: Mammon? The Guardian article notes that the Irish Constitution prevents those who don’t believe in God from serving as judges or as President. For more, see Michael Nugent’s post here.
