IMHO.. the teacher “acting as an agent of Government” way overstepped... I can’t stand the fact that schools teach “billions of years” and “big bang” garbage as if it were fact.. but calling TRUTH a lie and calling a LIE truth is overstepping... IMHO
Because the teacher is preaching in favor of the absence of religion doesn't mean this is not like trying to get students to convert to Islam, Judaism or Christianity. He is basically trying to covert the students to become atheist.
With that, atheism is a belief. In fact it has become a religion as Darwin as their god. It's funny, these folks put just as much faith in theory as others put into their respective religion. It is faith because Darwin's theory is just that. Theory! So, being that evolution is not fact, their believe is based on faith. A sort of faith for those without faith.
