A woman has given birth The doctor comes into the room and says "I have good news and bad news. The bad news is the child has red hair and the good news is it's dead"
Why do you feel it is right to make fun of redheads?
It's not a question of life or death, it's just true. All red-headed people are stupid, according to science.
A lot of information about redheads is misconceptions that people tend to spread around. It would be good to learn more about it before you spread around wrong information.
