This is a bad move. What happened to freedom of speech? Thankfully Atheist Ireland have responded by publishing 25 quotes that they believe break the new law.
From yesterday it has been illegal to blaspheme in Ireland. Essentially, it is forbidded to be "grossly abusive or insulting in relation to matters held sacred by any religion, thereby causing outrage among a substantial number of the adherents of that religion" given the fact you "intend, by the publication of the matter concerned, to cause such outrage.”
