"Those who know they are right have no reason to stifle debate because they realize that all opposing arguments will ultimately be overcome by fact. Yet those who champion massive taxes and spending to fight climate change, for example, do not seem to understand that. If science is on their side, then why should they care who is against them? "The debate is over" is a line that's used only by those who realize they would never win a debate.
In the end, it is not the debate itself, but those preventing it that are truly un-American. Honest listening and, more important, honest questioning is the foundation of the American experiment."
