I listen to Mr. Limbaugh and agree with the majority of his opinions.
Bear in mind though, Mr. Limbaugh is (first and foremost) an entertainer (like Colbert or Stewart). In being such, they are all prone to exaggeration. Sometimes they cross the line into pure falsities.
It is incumbent upon each of us to listen to discussions and arguments, and then draw, each of us, our own conclusions based upon our own critical thinking - not thinking solely performed by another. Doing so wards off propagandists.
