This section of Boswell's work points up some of the structural flaws of his study, in my opinion. "Structural flaws" does not necessarily mean "incorrect data and evidence" but rather that the large-scale conclusions are shaped by the ways in which that evidence is interpreted. And in his quest to find evidence for the existence of a postive gay subculture, there are times when he is deliberately credulous (such as taking politically-motivated accusations of sodomy as descriptive fact) or fails to consider the meaning of the asymmetries in the data.
