Are purists those who have both interest/passion AND expertise in a particular area. I'm purist in my areas of expertise because I know the subjects inside out including the history, and I love where they come from and what they are. I'm paid to know and I'm relied on to know. Because of my intimate knowledge, I get a bit upset when history or identity or whatever is denied in re-interpretation. Also I know that whatever anyone else does with anything is up to them and their imagination and creativity. History like identity, doesn't stop - it continues as does everything else. Doesn't include or preclude anything else at all. Are we presuming that the word 'purist' has a value judgement implied? Given that, it seems also that there are very many open minds here. Love it!
