My first-grader was told by his teacher that Kwanzaa orignated from Southern African harvest festivals, and was required to make that minora-thingie from paper. We very quickly objected, on the basis that we never saw anything of the like while living there, and he was excused from further Kwanzaa indoctrination.
We must never forget that the vast, vast, vast majority of "teachers" out there are not qualified to teach our children. They are unintelligent and uneducated, mixing up people like Martin Luther and Martin Luther King. They are typically given a "certificate" by the government which says that they are qualified. That in and of itself is Orwellian.
I'm delighted that you straightened out the ding dong who professes to be qualified to teach. I hope others will follow your lead.
