I have to say, yes there are pure snakes in the hobby and you may be an owner, But, you are in the minority. While having a "pure" snake is what you want, and thats fine, it's not what the general public and snake owners want. The people paying the money want a snake that looks different. Thats the area that is growing now, not "pure". It's great you want to keep and breed "pure" snakes with the few others like you.
