2) A society of the same mechanism (i.e. the group in control of the society keeps others from being successful) within another culture (i.e. India, caste system)
3) Commonly confused with prejudice, bigotry and bias, which can be exhibited by any individual in any society. Racism has a different connotation associated with the person being able to use prejudice, bigotry and bias to, for example, kill someone because they were black (and "inferior") and THEN be acquitted at a murder trial with a racist jury and a racist judge. A black person committing this crime out of prejudice, bigotry and/or bias would not be acquitted by a racist jury and a racist trial...in fact, they probably would have executed the black person and realized the cops just picked up a random black man off the street (because he was a black man), so they executed the wrong person. If it was a black-controlled society with white people systematically being executed for committing crimes they didn't commit, one could argue that that particular black society might be racist.
A lot of people on this thread were probably called racists and decided to deflect the definition of the word back on the person who called them racist INSTEAD OF trying to understand why people are calling them racists. Please ask why and they might explain. Racism is EXPECTED...A NORM...for minorities in the US and Europe...when someone calls you a racist, they are letting you know that you are an extreme overt manifestation; perhaps discussion will result in mutual benefit...perhaps your statements were misconstrued...or perhaps discussing it will help you realize how racist you truly are...the first step is acknowledging that you have a problem.
2.(adj) the state of being a racist
usually caused by lack of social contact with the race they hate/dislike thus can only assume what they've heard about that race to be true OR the person has had a bad social experiance with that race thus causing the person to asosiate everyone of that race with that bad experiance and assumes everyone of that race will be the same.
"I hate you because you have blue eyes" and 50 people with blue eyes were hung.
The other racist said:
"I hate you because you have black hair" and 50 people with black hair were hung.
The third racist said:
"Wtf you guys are white, you should die then" and 100 white people were hung.
Later, all the racists were hung for crimes against humanity.
