One could analyze the major Japanese novelist Yukio Mishima in the same way, but Mailer, who has grown ever more feeblemindedly male supremacist over the years, has saved us the trouble by providing worshipful writings about Mishima's obsession with manhood, militarism, and death, his contribution to the Mishima cult of necrophiliac androlatry that has sprung up since the latter's suicide.
