I don't use the word 'Caucasian' and have always thought it a bizarrely specific place to attach to white Europeans. However, I don't agree with this, "Every time you identify yourself or others as “Caucasian” it becomes a reflection of Blumenbach’s belief in white superiority. " People use words all different ways and the meanings change over time. Someone who has never heard of Blumenbach (the vast majority of people, I'd wager) who use the term 'caucasian' mean nothing other than 'white European people.' The fact that it was coined by someone with another agenda doesn't mean that that meaning has stuck to the word or takes on any reality for people using the word today.
