I think that what he meant, is that it is natural for people to feel apprehensive at the "dreaded other" and that everybody does it at some degree.

Of course, it is not okay to know you have negative feelings to others and let them be. Most people don't know they are stereotyping others. For example. If I think all gay people are fabulous, I am stereotyping them but I don't feel or think that. Because, you know, all gay people are fabulous.

Still, CIR is right, we are for many people the dreaded other, stereotyped and even hated. Thus, it would be hypocritical to have negative or unjustified feelings towards others while demanding to be judged as individuals.
