Stereotypes aren't even remotely accurate. Black penises are NOT large like certain racial stereotypes indicate, and I assume asians don't have micropenises either. The kinds of people who perpetuate condescending stereotypes and make very sweeping overgeneralizations are biased and usually have something against whatever ethnic group it is that they're commenting on, therefore there's no reason to believe them.The same goes for unrealistically good stereotypes that overglorify something as well, like "all asians are great mathematicians".
Well the asian micropenis thing must be at least somewhat accurate... Because I've seen alot of micropenises in asian porn. Unless they have some sort of reasoning for hiring pornstars with micropenis, that has to say something.
