Is being stupid a learnt behavior?
When you are taught to reason irrationally at the same time you are being taught to be stupid. To be stupid is worst than being ignorant. When you are stupid the only help for you is the help of God.
Black Americans from early adolescent, childhood were taught to be stupid when we were taught to believe in the Jewish Jesus who is not a Black American as we are.
The different with the Muslims is that they saw no benefit from believing in the Jewish Jesus and so they moved over the Arabs, but that was wrong as well since Mohammed was not a Black American as we are.
No Black American was intelligent enough to know that Black Americans must have a Black American prophet as the Jewish Jesus match the race of the Jewish people and that Mohammed matched the race of his Arabian people.
So, can a people be taught to be stupid? The answer is absolutely YES!
The question now is how long will Black Americans who claim Christianity and Islam will stay stupid now that we a have a genuine Black American Prophet Harry to lead us into our own of everything?

Like all good Attorneys, you knew the answer (you wanted) before asking the question.
