Why do a lot of white people think only blue eyed and blonde haired people are white or Irish? Reguardless if libs or cons?

Question

Why are so many people still so ignorant? 

I also still.see people who think pale skin makes a person white or blue eyes?

There's lots of dark haired, dark eyed white people, and even Irish and German, who also can tan.

Is it just an ignorant hick mentality? Or inbred? 

Update:

Edit:I also found non whites to believe this.

Blacks, Chinese, Hispanics. 

Answer 1

You know something a lot of people don't. Great. Don't insult others for not possessing that knowledge. Life is a learning experience, you know.

Answer 2

Why does this worry you? Hell, I'm of Irish decent. But yes, I'm blue-eyed, but the gray is taking over the blonde. 

Answer 3

Thank you for displaying your racism. Clarity is more important than agreement. People who don't care about skin color, hair color, or eye color, are the true non racists.
