I agree with all of you, if we were talking about race issues, the reason i added the definition of prejudice is because i anticipated responses of this nature. My original idea was that prejudice is biological, (due to the way our brains automatically categorize similar stimulus; for better or worse)
racism is the cultural byproduct of prejudice. Race is just a noticeable difference. Even in societies where the race is homogeneous, there is always a noticeable attempt at ethnic superiority, (see china) or tribalism(see Africa). We as humans tend to 'need' to see a difference between things, and put it into order of better and worse, and will create sub categories to fit such a system if a noticeable difference arises.

Once again i'm not saying racial prejudices is biological, and the cultural aspect of racism was going to encompass another post, i should have added more on this, generally when people think of injustice/pre-judegment, they think of race.

If you are truly interested in the topic, re read my post (with the definition or prejudice include at the end) and then logically rebut, i hope the replies don't turn into a broken record on a subject that i did not even intend to touch.

thats why i said omelets and not people.
