Pondgirl, I disagree with your reply to my question to Ed.
Firstly you have misquoted Ed, He did not say use the DM "for your opinion" he wrote  "(those that use the Daily Mail as a source of information!)". Using for "opinion" is totally different than using for "information."

Information being facts formed so as to provide meaning. Prejudice I agree as per your post.

Many people use the DM. to seek information. Nobody can assume that "those" who seek information in the DM. agree with the information or use it to form prejudiced opinion.
Some read it to disagree,
Some to understand.
Some to (know thy enemy).
Some to comment on.
Some to debate it.
Some for legal purposes.
Some for social purposes.
Some information in the DM, is 100% correct.
To label "people" whose motives or reasons are not known in a pejorative way ie. "prejudice" as in the post is to have an unfavorable opinion or feeling formed beforehand or without knowledge, thought, or reason of these people. I.E. prejudiced opinion of these people.
This is an good example of the insidious nature of prejudice.
The objective of this form is, consciously or unconsciously,  to take away peoples freedom to seek information and devalue them by labeling them in a pejorative manner.   :)
