I dont but that is an interesting quote alright.

However say in Ireland where the early Christain church built on sites that were supposed to be linked to whatever the earlier religion was, would this not mean that some of these megalithic sites that were reused would have also been used by Druids (if that was the religion between whatever the Neolithic/Bronze Age people and the early Christain people) and therefore the Druids did worship at fixed stone sites?
