the something starts with the assumption that one race can do something another race can't and it easily becomes definition 1, "one race is superior to another" and by definition "one race is inferior to other races" and that is what is commonly refered to as racism.
common examples are
all orientals must be smarter then all caucasions because they get better grades.
all blacks have a natural sense of rhythm.
all mexicans are lazy.
all blacks don't want to work.
all chinese are inscrutable.
all jews are good business men.
the "all," whether spoken or just tucked away in the mind of the "racist" is the bad.
it leads to value judgements about one group that is not true.
it does have one advantage. the "racist" does not have to know a person he/she meets, because the "racist" knows the new person by his/her race. it's the "all" that causes the problems between people of different races.
babies are born pure, they have to be taught to be prejudiced.
as difficult as it is, if a person can examine the prejudices he has been taught, and can understand the fallacies, that person will no longer say things like: joe lewis is a credit to his race, marciano was never refered to that way, for a mexican, he works hard, i once had a jewish boss and he was a nice guy, and all the other clichés that we use and take for granted as acceptable, when they are not.
understanding why other groups cringe at certain clichés, might eliminate those clichés from our
vocabulary.
Compay, i hope you understand why i was so angry at you.
