What is truly lacking is common sense...
A normal person would not take whatever is being fed them as prima facie truth...perhaps some lacked it from birth, but I contend it was breed and beaten out of people in their youth...
I always read a lot, always was skeptical of others certainties...
I guess now days it is easier to be lazy and regurgitate falsehoods than think for ones self...
Sad...and it condemns others to be infected by the same contagion...
