In relation to the possibility of being sued, one thing that might be of note is that blasphemy is currently illegal in Ireland! €25,000 maximum fine.

I believe a referendum is being held soon which will decide whether or not to change this - it is actually required by the Irish constitution that there be a blasphemy law. I think it is very important that the constitution be changed and the blasphemy law be removed. If you agree, please make sure to vote appropriately when the time comes.
