I never felt anger and I do not know how I would be when under that state. People are also curious as to how will I deal with that kind of emotion.
Please take note that anger and being irritated are two different things.
Have you ever been angered before? Why? What was it like?
How will INTJs show anger? How do you do it?
How long did it lasted? Did you regret it?
Have you ever encountered an angry INTJ before? What was it like?
If not, are you curious about it? Would you dare anger an INTJ just to be able to see it?
Are you intimidated or frightened by the idea of an INTJ being angry at you?
