Sex education should be taught at home but who is your friend and stranger should not be

Now days sex education is increasing being taught in public schools now we have Common Core.  Kindergarteners can barely learn their ABC and 123 which is what we do focus on with this group.  Not sexual body parts which most kindergarteners could not even say beyond like dog and cat.  I could see like the Chicago Police Department have two assemblies in the schools  teach the students who is a friend and a stranger.  This will help prevent childhood abductions and have the parent submit a list who is authorized to pick up child.  As a former taxi cab dispatcher I asked the either student's teacher or principal to have kid wait in office and have cab driver come inside if cab driver refused I inform you do this or you do not take these trips.  This would reduce childhood abductions.  Have a child get finger printed at the police station get a DNA swabbed no needles involved since most little kids hate needles just go into any doctors office.  Teacher the student the proper body parts that belongs at home not the school.  I understand a girls body starts changing at age eight or nine and a boys boy starting changing around 11.  Have them learn it from a school teacher at five that is ridiculous they do not even not how to tie their shoes yet.  Places like the Chicago Public Schools want to teach this in kindergarten come on.  We are teach kids not future pervert no wonder why we have children who become perverts as adults.  I hope the Chicago Public Schools have an opt out option if not pull your kids out of to private school or home school.  Parents should only teacher sex education when the child is not ready not when some stupid six figure administrator who does teach kids decides.  Come on America reject Common Core and anything that is not American and Apple Pie.  Public Schools was never part of state check constitution.  They say nothing about education funding in any way period.
