I'm not angry and I can't speak for all INTJ females, but I'd certainly suggest standing pretty far away when you laugh or ignore us so you can get a good head start when we come after you with the nearest large blunt object at hand.
And god help you if you lose consciousness at any point after we catch you. We'll probably take that as being ignored and it'll just make things worse. I can't tell you how many times I've found myself standing over the unconscious form of someone who laughed at or ignored me screaming "ANSWER ME BITCH!!!" and hitting them with a baseball bat before I realized they were incapable of answering. I understand that it's a common mistake for INTJs to make.
Obviously (I hope), I'm joking, but as I think we've already seen with this thread, we can be less than rational when provoked.
