Men, or gentlemen 
... the difficulty is getting unbiased facts when this discussion is so charged with a type of religious zealotry.
Even the schools have been a seeding and breeding ground for an ideology where our kids have been indoctrinated rather than thought to think critically about this issue. It has been 30 years in the making.
Today, those in government who are committed to the ideology are numerous enough and are ready to take taxpayers money for an idealogy that continues to prove itself inconclusive but whenever one questions the idealogy, those in power believe the inquiry to be coming from a person who has a two decimal place IQ.
Critical thinking is like common sense, not too common according to Voltaire.
