I agree with the assumption that ideology is an interested human construct. And it seems very crazy to me that an aesthetic drive can involve such a vital commitment as in the case of this literature genius, Yukio Mishima.
Yuki yearned for an imperial past because of that kind of homophobia that made him despise the lack of virility in men, motivated above all by his sexual preferences. It can be inferred that his fascist inclination derived from that reverie of his, populated by grumpy samurai, ruled by millenary codes of honor and, more importantly, fucking each other with military austerity and vigor. She tried to take Japan to the Middle Ages to fulfill his fantasy and as it did not come out, she got angry and took out her guts. This was Yuki, the greatest genius of Japanese literature of all time.
