The Modern Era (1875-1965) was very tolerant of criticisms of its rules - as long as your criticism played by those same rules.

Dozens of major ideologies - isms of all sorts and shapes - poured forth in that age - each vigorously disagreeing with all others, except for the Modern Era's one overarching grand narrative : that to make a credible critique of Modern grand narrative, one must have one as well.
It was not the time for guardedly measured criticisms : it was an age of Alpha Male ideologies and their Alpha Male critics : dream (and critique) big and bold --- or stay home.
Martin Henry Dawson differed profoundly with this world : perhaps most defiantly in denying the need for grand critiques against grand narratives.
As a result, he simply doesn't figure as an intellectual (by word and pen) critic of his era.
