Somehow, I cannot find these definitions in any dictionary, including a 1934 issue, far too early to have PC intervention.
Again, it's pretty much an obvious statement of fact that sheeple is merely a term for anyone who disagrees with how one thinks. A mirror-image of what we accuse the Leftists of doing to us.
How anyone with an IQ above an ice-cube can accuse entire sectors of the population of anything is ludicrous. Not everyone believes that your personal interpretation of the world is correct. They have other axes to grind. Be it automotive restrictions, safety issues, or access to state and federal land for recreation. They feel easily as strongly about them as us.
To their way of thinking, ignorance of those issues would therefore render the gunners, and reconstructive amateur Constitutionalists, into sheeple.
Hey, WE'RE ALL SHEEPLE!!!!!!!
