If publishers and editors exert themselves to keep certain topics out of print, it is not because they are frightened of prosecution but because they are frightened of public opinion. In this country intellectual cowardice is the worst enemy a writer or journalist has to face, and that fact does not seem to me to have had the discussion it deserves.
