Yes and no. It depends on what time, author, even the mood of the people you are reading from.
Wikipedia says "In various times and cultures, red hair has been prized, feared, and ridiculed." and "A common belief about redheads is that they have fiery tempers and sharp tongues. As in Anne of Green Gables.https://en.wikipedia.org/wiki/Red_hair
On the other hand, the "gingers" are also seem as people that stand up for themselves
- with a positive ring
to "stand up for themselves" here.
As Elizabeth Euberg, author of Take a Bow, points out: But redheads, she says, are generally assumed to be characters who stands up for themselves and others, who are energetic, who have some version of the fire exampled by their hair color. Maybe this is a stereotype—but it does seem to be a pretty positive one, if so.http://www.theatlantic.com/entertainmen ... on/326680/
The same goes for blondes, the ones with vivid black hair, the ones with wawy or curly hair, the ones with...Stereotypes knows no limit!
Perhaps redheads stand out because they make up only 1-2 percent of the population, but then certainly the first Japanese that came to Brazil were a sensation of sorts, as were the first Italians, and others.
And vice-versa a Brazilian would be watched closely, for the worse or for the better, in Japan or in Noruega. And in Noruega the blondes don´t stand out from the crowd.
Fact is, the human being see with suspicion and fear the other that is different, but then watching closely he/she can see positive traits in the different sooner than in the ones that he simply doesn´t see closely. Provided that he/she isn´t biased, of course.
