No, the sentence "You are prejudice" is not grammatically correct. Prejudice is a noun, and you is a pronoun. The sentence essentially is saying that "you" are something that you can not possibly be - the noun prejudice. To make the point you're trying to make, you need an adjective to follow the verb "are." Prejudiced is the descriptive adjective form of prejudice, so the grammatically correct sentence should be "You are prejudiced."
