I don't follow your definition of ignorance. There are plenty of things I am ignorant in: how to build a house, how to read War and Peace in the original Russian, how to integrate using anything other than a Riemann integral. The default state is for me to not know these things. Yes, I get why people would be mad if one were to be proud of not knowing what a Lebesgue integral is, but the celebration of ignorance is different from ignorance itself. In other words, ignorance is not bad per se; it's just a default state one would hopefully grow out of.
