It is wrong to say that heresy and heretics do n`t exist, because the Bible clearly talks about heresy, heresies, heretics, false teachers,
false teachings etc..
; instead, what is needed are better
teaching, improved students, less memorization and more learning to increase understanding, instruction about problem solving, instruction to counter the
false Hollywood message that science and research are entertainments,
teaching children and adults how scientific research is very important in the daily life of all people,
etc..
