See that is exactly what i mean... you just compared somebody who has been ignorant and rude to someone to murders and rapes. Somebody else suggested that her kid will grow up into a Hitler (is that a proper noun?). I will not comment on whether what she did is a crime, i am sure she will be prosecuted if it is. However, i do like your own example. Of course people who break the law are responsible, in the western system they are normally removed from the society so they can not do that again... though notice how some other people still continue murdering and raping, which suggests that certain people, when placed under certain conditions, do certain things. Of course we can have a long discussion how nazis, personal responsibilities, right and wrong but it changes absolutely nothing. In fact, as a result you hate a group of people. From your own example you clearly differentiate hate based on the way a person is born (race, nationality, etc) and hate based on the way a person acts... but the thing is: you can not expect other to stop hating till you will do the same.
You want to make a difference? find somebody who is ignorant and angry and help them.
