Well she is not aiming to have the hindu, syke, muslim, prods, atheists or anyone else.she dreams of a Gaelic or at least an irish island.
Except that the Gaels you mention had radically differing views from those espoused by the CC. If we could all agree that the Brehon laws were actually incredibly progressive in the context of their time.
I believe G O'D to be blinkered on the subject. There is an incredibly strong attachment to paganism on this island which has never been completely let go. The CC just kept a lid on things, so to speak.
The beliefs of foreigners on these islands are of no interest to me personally - provided they are kept private. Eid prayers in Croke Park are offensive beyond words ( but then I do understand Islam)
