I don't like it either, Nick.
My tolerance of it does fluctuate depending on what kind of ignorance is coming out of a person's mouth.
On the other hand, I have contributed my share to the problem by playing a "dumb woman" part because it got me successfully through certain social situations when I noticed that showing my intelligence was hurting me. I wish I was strong enough to have stood by my true self and not caved to a bs stereotype, but I'm not going to deny that I made the mistake.
