Nothing wrong with being a purist.
Nothing wrong with not being one, either.
Why does one have to choose?
I love traditional music: English, Irish, Venezuelan, Greek, French, Scottish.
I also love other music - too many types to list. And I dread to think that if I was a purist that did not listen to other music, then I would have missed:

"Lies" and "The field behind the plough" of Stan Rogers
"Sir Richard's song" (of Peter Bellamy's?)
"Sally Free and Easy" of Cyril Tawney
"Chicken on a raft" of Tom Lewis
"Fiddlers Green" of John Connolly
"Where Ravens Feed" of Graham Miles
"And the Band played Waltzing Matilda" of Eric Bogle
...and dozens of others, precious jewels all, that please the ear, lift the heart, quieten the beast and foster belief in humanity.

But your choice - nothing wrong with it.
