What is a "purist"?

First comes the music. Then someone makes up the rules.

It's simple. If you don't like a certain music it means:

1. You don't know enough about it.
2. You have prejudices.
3.   You may understand some music and still not like it.
4. You may attribute to it false subjective standards.
5.   You've got an axe to grind.
6. You haven't listened to it long enough.

What I hear in John C's statement is that he has been criticized for liking certain music or mislead in the adverts about what the music was supposed to be.

If he defines the kind of music he likes as "purist" then how can anyone argue with this? There's nothing wrong with that.

i don't have any problem with music that I like or think is good.
Why should anyone else?

But it's intolerant to judge another person's taste in music just because you don't like it.

I don't like heavy metal or some hip hop but I'm not going to say that it's not good music. In fact I admire much music that I don't like because the expertise that it takes to produce it in my view is to be admired.
