In other words, do peoples' prejudices arise from their fears, phobias and hatreds?
For example, "I hate spiders" could really be saying, "I have arachnophobia". But could it also mean, "I am prejudiced against spiders".
Then of course, we have the situation of homophobia, literally meaning the fear of homosexuals and of course also, as we all (should) know, homophobes hate homosexuals and will have an innate prejudice against them.
Is it possible that here are people in this world who hate all other people who are not like themselves and therefore be fearful and prejudiced against them?
