Do you mean prejudiced? I think you must because prejudical means....oh heck, let me just give you the definition. Pre*ju"di*cal\, a. Of or pertaining to the determination of some matter not previously decided; as, a prejudical inquiry or action at law.

a prejudiced example is you must be uneducated because you can't spell

A prejudicial statement is a preconceived idea or conviction that judges without all of the facts, usually said in favor to support their beliefs or ideas.
Nonprejudicial statements do not include discrimination or bias.

Prejudicial Example:
“A woman will never be able to reach the top of the professional ladder that seems to be held up by men”

-Claims that women are not intelligent enough or cannot reach the potential that a man can in the work force.

Non Prejudicial Example:
“There are many companies in the US that have made a strong effort to promote both men and women equally.”

-Does not single any particular group and includes both men and women.
Based on factual documentation

Do your own homework! lol
