8 Asians has a wonderful article that discusses this strange stereotype with "The Perfect Villain: Straight Asian Men" :

We Asian women never say generally “men are horrible.” We say “Asian men are horrible.” We ourselves buy into the rumor that somehow Asian men are more misogynist than other men. The complaints ring universally: Asian men are more abusive; Asian men are more chauvinistic; Asian men are weak; Asian men fail to protect their women. Why?

…

Why don’t we take straight APA men seriously? Is it a matter of invisibility? No. We see them. The truth is, we don’t really like them. They’re villains. They represent male dominance. Heterosexual dominance. And before anyone can do a doubletake on the logical fallacies there, we got the waves of APA women feminists who reinforce the villain archetype with narrative after narrative of straight APA men who fail to protect women, because whether or not we realize what it is we’re doing (*cough* traditional gender roles *cough*), at the heart of it that’s what women want: men to be protective. So it isn’t that Asian women believe the crazy villain stereotypes of Asian men; it’s that we don’t necessarily see them as protective over us, and so subliminally it’s easier for us to buy into the overt stereotypes, or worse yet, generate them, and then proceed to ignore and dismiss the rational straight Asian men who challenge those stereotypes

What is it that creates this very dominant stereotype? in your experience – is there any "truth" to it?
