Buddhist exclusivism in Sri Lanka

Is this modernism, exclusivism or fundamentalism? I’ve got a chapter coming out (in Sharing the Sacra, ed. Glenn Bowman) in which I discuss local responses to a similar attitude among Pharping Tibetans, but this is sharper still. While recent academic study of Buddhism shows that it has always included deities of various flavours, the uncompromising attitude shown by the author of this peace gives me little hope for flexible, collusive processes such as those I documented in Pharping. Surely Nāgārjuna was right to list worshipping the worship-ables right after the ten precepts in his Ratnāvalī.
