Why do foreigners hate red hair?

Because foreigners think it is unlucky to be born with red hair, and the most famous redhead in history is probably Judas who betrayed Jesus in the Bible, so most westerners are religious, so they don't like hair of the same color as Judas (because it is unlucky).

Historically, redheads have been discriminated against in many countries. In ancient Rome, redheads were treated as slaves. In French Corsica, if you meet a person with red hair in the street, you should spit and turn away. There is a French proverb that people with red hair are either violent or hypocritical, usually both.

During the reign of the Spanish Inquisition, a red hair proved that you stole the fire of hell and were going to burn. /kloc-In the middle of the 0/9th century, a sudden famine in Ireland led to a large number of poor and hungry Irish immigrants to the United States. Like Scots, Irish people have a lot of red hair.

America is a Protestant country. There are religious differences between Americans and Irish immigrants who believe in Catholicism. They think these red-haired Irish immigrants who believe in Catholicism are poor, alcoholic, irritable and dishonest.

Extended data:

1. People born with red hair account for less than 2% of the global population. Red hair was "created" by a genetic mutation in northern Europe thousands of years ago. Today, with the development of globalization, the geographical selectivity of mate selection has been broadened, and the chances of redheads meeting together have decreased. Therefore, few descendants of redheads are born with "redheads" or "redheads".

2. If one of the husband and wife is born with red hair, the baby they give birth to is light yellow hair, but if both husband and wife are red hair, their children are more likely to have beautiful red hair.

People with light yellow hair should move to Scotland if they want to save themselves, because Scots have the largest proportion of red hair in the world. It is estimated that 40% of Scots carry the red hair gene, while 13% of Scots have dazzling red hair.

National Geographic magazine pointed out that people think that the red hair gene is beneficial to human body, and it can improve the ability to produce vitamin D in sunlight. Nowadays, the red-headed gene is more prone to induce skin cancer and is highly sensitive to cold and hot pain.
