Carl Marx wrote an essay on the question of whether communism would conquer capitalism in a WAR. His thought was that it would not be necessary. THEY WOULD TAKE OVER THE SCHOOLS. Clearly, out LIBERAL TEACHERS UNION is doing the job. That and the fact that kids today are raised by Sesame street and Barney.
Assuming your quote is correct. When I question my own prejudice I reverse the facts to see what would occur. Had the teacher said BLACK STUDENTS ARE BORN ................. she/he/it would be tossed out.
