Oh??
Why?
Because to protect it from claims of being neo-creationism, IDers like to say the "designer" isn't specified. Therefore, others are free to state what they think the designer is, such as the Flying Spaghetti Monster.
Thus to deny Flying Spaghetti Monsterism is to deny ID. To support ID and deny FSM is not consistent, and exposes the true neo-creationist purpose of ID.
