What writers should a good writer avoid getting tainted by?
The list discussed at the link is all about protecting the delicate sensibilities of novelists. To write, you need a good "ear." (Sorry, that's a metaphor. And a penchant for metaphors is something you might pick up from reading "Blood Meridian" by Cormac McCarthy.) The problem with reading is that it puts some author's way of saying things in the place in your mind that would otherwise be occupied by the way real human beings speak.
I think you can immunize yourself from the disease of overly influential writers by getting out there in the world listening to people and doing some talking yourself. Have conversations. Listen to other people and watch how they interact with you when you speak. Develop your voice in real life. Even if you don't end up with a good ear and an original writing style, you will have lived and you'll have your friends. Maybe even some stories to tell.
So put down that book...
... and go parading before it's too late.
And stop looking so scornful, it's twisting your face.
