I lose a significant amount of respect for people who do this. I despise it, and it is done by people ranging from Dr. Victor Davis Hanson (who I admire greatly) to this author.
The term "Red Scare" is universally used where it is asserted that Communist infiltration was NOT a real problem, but was propagated and enhanced by people (such as Sen. Joseph McCarthy) for rank political gain.
Communism infiltration was a real issue in 1930-1953, and today, need I mention what kind of problem it is in the hands of the Sixties radicals and their ideological descendants who cut their hair and put on business suits, and have had their hands on the levers of power since 2008.
I find that annoying, too. I guess they do it as a simple reference to what was going on without any thought to the validity of it.
My understanding of what you wrote:
The term “Red Scare” is universally used where leftists assert that Communist infiltration was NOT a real problem. Leftists assert that a “Red Scare” was/is propagated and enhanced by people (such as Sen. Joseph McCarthy) for rank political gain.
Did I get that correct? Tx.
Film from the era: Blood Alley, starring John Wayne and Lauren Bacall

I think Steyn would agree that Communist infiltration of Hollywood was real, but along with Ford that censorship of the kind DeMille was apparently suggesting was not the cure. Anyway, that’s my take.
