You’ve got it completely backwards. I’ve never blindly accepted the media reports, including when they happen to say good or bad things about people such as Joe McCarthy. The facts are that Joe mcCarthy served in the pacific with a Marine Corps air unit in WWII. Unfortunateely he engaged in some stolen valor by falsifying intelligence reports and other documents for the purpose of obtaining decorations he had not earned. In other words, McCarthy engaged in some highly dishonorable lies and deceit at the expense of his fellow combat veterans.
Did McCarthy’s opponents then and today slander and defame McCarthy in largely successful efforts to discredit McCarthy and all anticommunist criticisms? Yes, of course they did so, and they are still doing so today.
Are you going to argue that wee must overlook MCarthy’s despicable lies and dishonor because he attacked the Communists, or do you suppose his legacy is perhaps a good warning that his conduct regardless of true motives was unacceptable and counter-productive to effectively opposing a Communist overthrow of the American constitutional republics?
