From someone who should know better:
Especially in metal music, I find that a lot of people can be very closed-minded – Derrick Green @ Sepultura
Another term for closed-minded: having made a decision. Knowing what one likes. Clear and goal-oriented.
People like to use the “you’re just closed-minded” as a way to force you to like whatever it is they are doing.
The fact is that even an open minded becomes closed at some point, once it has made its decision.
Otherwise, it is capable of nothing and sits in perfect suspense, making no decisions — a rape target for miles around.
Derrick Green should know better. He should be, how shall we say, “open-minded” about this issue.
