Sorry, you're just using a made-up definition of prejudice. In the actual definition of prejudice, yes, group-level conflicts invariably require prejudice, because you presume the motives of an individual from that individual's group affiliation.
I am not using a definition of prejudice there at all, I am taking the definition of prejudice and attempting to actually comprehend what prejudice actually *is* as opposed to simply what it does. Or to put it the other way round, I am trying to understand the underlying mechanics behind what makes prejudice.
To my understanding, the core of prejudice is the confusion between two kinds of groups, integral groups which are groups that constitute compound objects and classification groups which are a number of things that are grouped together because they share a given set of traits. The reason these things become conflated is because traits can in many contexts imply a membership of a integral group, which makes it possible to forget the two things are actually not the same thing. No prejudiced person will ever comprehend what I am saying, because to actually comprehend the difference is to cease to be prejudiced.
In VislarRn's earlier example the Red Order and White Order are examples of integral groups, groups with leaderships which carry out particular unified policies, like massacring people in the former case; things to which they may be held collectively accountable. They wear red and white clothes respectively, 'people who wear red clothes' on the other hand is a classification group not an integral group, the mere fact that two people wear red clothes does not in itself imply any common relationship to anything else.
The thing here is it is entirely possible to be hostile to a classification without being prejudiced, provided that what you are hostile to is part of the classification and you have a rational basis to be against it. While vampires in DF are a classification not a integral group, but it is not prejudiced to be against them automatically because them drinking your blood is part of the classification ITSELF.
you could just download them from the internet but yes, we do want that. Everyone is allowed to publish their opinions. That is how freedom works.
... More importantly, though, none of that applies to The Bell Curve because the idea that it's "a racist book" is a myth.
If the Bell Curve is not a racist book, then I am rather wondering what a racist book actually is.
In freedom people are allowed to write stuff and say stuff. They are however not necessarily allowed to publish stuff, because publishers are not compelled to turn any particular person's work into a published book, that being because also being free *they* also have the freedom to *not* do so. Equally, once published we are quite allowed to rely upon the general word of mouth regarding the book in question to criticise it, when reading the book will support those societal elements which we do not approve of; those who have read the book can always correct any inaccuracies there are provided that freedom exists (as you put it).
Aside from actually stealing a book, there is very few ways to actually read a book without at least promoting it. If the book is downloadable online for free, which is not the case with the Bell Curve (a copywrited work), then by downloading it you are still increasing the profile of the book relative to rival printed works by giving the book more downloads and views.
