The problem with this is that Protestant (or muslim) schools will be also unviable without any government funding. This was one of the reasons for
FG's objection to the withdrawal of gov money from fee paying schools.
Do you really advocate an Ireland in which no one can get an education of their own exclusive religion ethos, be they Church of Ireland, Methodists, Presbyterians, Catholic, or Muslim?
Secondly, I don't see why a school can't teach on "particular issues on which society disagrees" (what exactly???). Should minority religious teaching be not taught if it doesn't agree with the majority's view on some issue?
And finally, ANY social agenda will exclude many teachers, parents, and students. Would you object to a liberal social agenda being taught because it would exclude Catholic teachers, parents, and students?
