Acroterion, I don't believe I need to review or post what a broad cross-section of scholars have to say on the subject.  I believe a 5th or 6th grader could determine the relevance of the facts I propose to post.  

Plus, you are imposing an impossible standard in that most scholars don't state the obvious for obvious reasons.  Why should an accomplished scholar say 1 + 1 = 2 when everyone in his or her audience already knows the answer?  

Here's a reasoned conclusion a 5th or 6th grader could arrive at: Since Fisher's affiliation with the National Lawyers' Guild was already public knowledge, McCarthy didn't do anything wrong by mentioning Fisher was affiliated with the National Lawyers' Guild at the Army hearings. And Welch was wrong to denounce McCarthy for saying that.  I'm not proposing to say that, but the conclusions are inescapable for even a 10-year old.

I do not doubt your good faith, but your analysis and reason appear weak.  No one besides you has raised that objection.

Are there others that join you in raising that objection, because I'm not convinced anyone besides you believes that?

BTW, this appeared on the Army-McCarthy hearings site:  "At the time Brownell was seeking to designate the NLG as a Communist front organization, and McCarthy mentioning Fisher's membership violated a pre-hearing agreement to not raise the issue as it was still being litigated." 

This bald-faced assertion did not have any citation, raising suspicions it was just unfounded rumor & innuendo.
