All joking aside, this is a very real subject that our country, (The US) struggles with and I'd suggest that there's an under-current of racism that permeates any/all interaction between different ethnicities. Who here hasn't thought in the back of their mind when they see an inter-racial couple, (black man, white woman) she's probably with him cuz he has a big d!ck? Or a white guy with an Asian woman cuz she has a small pu$$y. Clearly, the more informed you are and the more interaction you have with various races, you realize these stereotypes are hurtful and oftentimes untrue...but there always seems to be that nagging little voice that creeps in and discounts other human beings based on these biases.
