After some serious research online as to what makes up a real Conservative, I've come to the conclusion that they possess great knowledge on any number of subjects. Just read the comments below any posting or newspaper article that invites an angry right-winger to set the record straight -- or to reaffirm what was stated in the 'above'.
They are experts on, but not limited to, the following....
The Sciences (don't exist)
Liberal Arts (but, as we all know, only Liberals take "Liberal Arts")
Note: I left out Philosophy as that may invite Semantics; and Pragmatics.
