Wow. Your ignorance is amazing. Quick history lesson for you. Once upon a time people were referred to based on their country of origin...Irish, English, German, etc. There was a time in America where Irish people for example were very heavily discriminated against. Then one day someone decided it would be best to combine all these people and call them "white". Because after all even though they might have disliked Irishmen, they were STILL better than "black" people! The reason why white women have so much variance is because they are truly different ethnicities, but we simply CHOOSE to say they are all the same. This is done with Asian people as well.
