WHAT IS PREJUDICE ?

Is it not liking something ?

Is it preferring one thing over another?

According to Wikipedia …

“Prejudice (or foredeeming) is making a judgment or assumption about someone or something before having enough knowledge to be able to do so with guaranteed accuracy, or "judging a book by its cover". The word prejudice is most often used to refer to preconceived judgments toward people or a person because of race, social class, ethnicity,age, disability,obesity,religion,sexual orientation, or other personal characteristics. It also means beliefs without knowledge of the facts and may include "any unreasonable attitude that is unusually resistant to rational influence."

The Dictionary.com version ...

“1. an unfavourable opinion or feeling formed beforehand or without knowledge, thought, or reason

2. any preconceived opinion or feeling, either favourable or unfavourable.

3. unreasonable feelings, opinions, or attitudes, especially of a hostile nature, regarding a racial, religious, or national group.

4. such attitudes considered collectively: The war against prejudice is never-ending.

5. damage or injury; detriment: a law that operated to the prejudice of the majority. “

The legal inference (5 above is not part of this topic).

The essence in these definitions is that prejudice is based on ignorance.

Does this then mean then, if you hold a view or preference or behave in a manner after having gained the knowledge, you are not prejudiced?
