Some people have a way of making broad generalizations about entire groups of people, and then saying those things in what sounds like a reasonable and friendly tone of voice. This can mislead many others into thinking that the ideas themselves are reasonable.
For example, such a person might say, in a reasonable sounding tone of voice, that black people are inherently violent and incompetent. He might add that all black women in particular are stupid, and could never, on their own merits, be in positions that require intelligence and competence.
Or he might say that Jews are secretly organizing a vast conspiracy to replace white people by “inferior” races. This is the same theory that Nazis adopted, and most people today don’t think that Nazis were reasonable. But apparently, if those same hateful ideas are advanced in what sounds like a calm and reasoned tone of voice, they can gain traction.
Here is what I am wondering: How flexible are these techniques? Could they be used to target Italians, or left handed people, or people with red hair?
Could a persuasive person, speaking in what sounds like a calm and reasonable tone of voice, get millions of people to espouse virulent hate and contempt against any particular group?
