Ctrwtf, I actually thought that Sinclair was pretty light on Russell.
I like his little footnote after his very brief mention of Russell:
P.S. A few months pass, and while this book is going to
press, “The Finished Mystery” is suppressed by the government
and several score “Bible Students” are landed
in jail for sedition.
I lost my notes I had made on the Golden Age articles, but I seem to remember that Upton Sinclair got a plug for his book Brass Check in one of the issues. The early Golden Age magazines published many articles supporting socialist views.
