And why is their ignorance something to be acknowledged and/or accommodated?
Take any human on earth and s/he will be ignorant of at least 99% of the sum of human knowledge. Accommodating ignorance is the only way humanity society can function.
I have a daughter who is in her sophomore year of high school, and a daughter that is planning to start her freshman year of college in September. I'm going to tell them both, "next time you have a question at school and don't know the answer, write down 'Any one person is ignorant on 99% of the sum of human knowledge. Please accommodate my ignorance on this question, as being the only way that humanity can function.'. I'm thinking that's not going to work.
More seriously, there is a difference between the systematic ignorance of the species and a willful and knowing ignorance on a specific issue on which that person acts. If she is going to be ignorant on that, and acknowledge it as an excuse, then she shouldn't be acting with such zeal. That's ALSO part of the "functioning human society" tradeoff.
