Amazing how knowing the backstory on something changes the light in which you see it, isn't it? If your audience doesn't know the history of an idea, you are free to twist it into whatever form you want. Therefore educating people is scary for those who wish to rework ideas.
Of course, education where people are required to read the sources, as opposed to the interpretation of them by those with an agenda (right or left), is truly scary. The value of a Liberal Arts degree!
