I've long felt that Yeung Gor had a slightly effeminate personality...not in the same sense that a Qwai Fa Bo Deen practitioner would be effeminate. Yeung Gor was no she-male, but he had a, shall we say, unusually feminine-leaning worldview for a man of wulin.
I attribute this personality trait of Yeung Gor's to the fact that he generally grew up under the care of women. Father figures were either unavailable or defective in one way or another. Yeung Hong died before Yeung Gor was born. West Poison Au Yeung Fung's association with Yeung Gor was brief and besides, the man was out of his mind. Gwok Jing *could* have been that father figure, but there were too many underlying problems (i.e. Gwok's connection to Yeung Hong's death, Wong Yung, Gwok Fu, etc.). Chiu Tze Ging was terrible in every way.
Yeung Gor lived with his mother, Muk Lim Chi, until he was around ten or so. From there, it was several years on the streets, six months or so with the Gwoks, and another few months at the Cheun Jen Sect. After being adopted by Granny Sheun and Little Dragon Girl, he found the stability he had yearned for.
Thus raised almost entirely by women, Yeung Gor developed a feminine worldview. It would influence his personality development well into adulthood.
But what if Yeung Gor had, like Gwok Jing, grown up in the ultra alpha masculine milieu of the Mongolian warriors? If Yeung Gor had grown up on the steppes as Gwok Jing did, hunting and engaging in war with other men regularly, what kind of man would he have developed into?
