Yes, I think you almost got it right. Although more precisely it is not so much that conservatives are uneducated as it is that the uneducated are conservative. Bearing in mind that “uneducated” is a euphemism for “Unenlightened”. And if one is conservative, uneducated and has a smidgen of religion, they are therefore unenlightened.

But, to be on the safe side, stay paranoid (because total global enlightment can only be achieved via a purge).
