Ignorance
Okay just for starters, this is why something like WET would'nt work.
Classify what is White.
If you say it is everything which is not Black, well that is wrong because there is a lot of people who are not Black but yet would not consider themselves White (Latins, Asians, etc).
Okay, then it is everybody who is a Anglo Saxon Protestant whose decendents come from Western Europe. Well that is wrong too, because there are a lot of people who are not either Protestants (Catholics, worlds third largest religion) or Anglo Saxons (Irish, Italians, Spanish, etc)
Okay, then White must be all those natural born americans who were not decendent of slaves or it the indegenous poplulation. This is wrong too because that could be pratically anyone.
White, Black, Latin, Asians, and all the other ones that can be posiblely be thought up, refer to culture, not race. Culture is about certain specific values, history, and biology that a group of people share in common. Something like BET picks certain specific elements of that culture and creates a picture of it. Obviously, since it is only specific elements, it can not be a complete picture.
A great example is Martin Lawrence. We all know his show and his schitick. He is what most people would call "Black" for better or worse. Despite this, I hardly think him to be typical of someone who considers themselves Black. He simply uses certain specific sterotypes common to those who consider themselves to be Black for comedic effect. Also, these stereotypes are only good for here in America, not in say Africa, where probably most of his jokes would be met with confusion.
To think in terms like Black, White, Latin, Asian, etc, in many ways is useless. Yes all people have a specific culture they come from and which they adopt, but it is hardly though indicative of who they are as individuals. Racism is an ugly word tossed around too much. Simplely enjoy the diferences between cultures, and bond with individuals though your similarities. Don't get drawn into others negativity and ignorance.
