from Fancyclopedia 2 ca. 1959
Fandom has remained remarkably free of political discussion within the frame of the US party system, considering how widely its members' views diverge on all other topics. Senator McCarthy's corsair cruise inspired a few articles con, but his defenders were too few and feeble to provoke a real feud; the fan press is not a good medium for political propaganda anyway. On the other hand, some intense differences of opinion have been manifested in the infrapolitical realm of social problems and their cause and cure, but for that we refer you to other sections. Discussions of these subjects were called "politics" in such old-time slogans as "Boost Science Fiction Not Politics" but they're really sociological.

In expressions as Fanny's "Boost Science Fiction Not Politics", means sociological discussions.
