I'm aware that just about every pro-conspiracy book on the JFK assassination that has mentioned Senator McCarthy has condemned him. Mark Shaw's important new book Collateral Damage is a good example of this. Many JFK assassination conferences will have at least one speaker who will condemn McCarthy and "McCarthyism."
It's curious that JFK/RFK/MLK assassination researchers know that most of the media and most "orthodox"/"mainstream" historians are usually unreliable when it comes to political assassinations and government cover-ups, yet they uncritically accept the "orthodox"/"mainstream" portrayal of McCarthy without even thinking about reading the other side of the story on him.
