As a parent, I want to know and understand what my children are being taught and why certain ideals or beliefs are being brought into school. As a former public school teacher, I saw many things happening in the classrooms; but, I never dreamed I would see classroom teachers and administrators pushing personal agenda's on their students. Our children need to be taught the basics at school. We need to focus on reading, writing, social studies, science, and arithmetic and leave the parenting to the parents.
