Not really. I have red hair because my grandfather and dad do. It's hereditary.
It may have started that way (just as it's theorized that blue eyes did) but now it's passed down the way any other physical trait is.
And there's tons of ginger jokes in America, too.
I get teased for it all the time. It's just friendly, though. Not as if anyone actually looks down on me for my hair color.
But apparently in New Zealand there's real prejudice about it.
My cousin lived there for a while, and she said that her redheaded roommate had a difficult time with it.
Once after..hmmm...spending the night with a guy, the guy woke up the next morning next to her, looked over at her, and said disgustedly, "Not a GINGER!" and got up and left.
So I won't be making a trip there anytime soon. Hahah
