This indeed went out under Falwell's signature but was a direct mail piece that he apparently did not write, and which he retracted when criticized. He certainly can be faulted for his view, but a note of the circumstance and retraction would be more honest.

I could post a long list of horrifying quotes from various communists.
Demonization is neither analysis nor discourse.
