In modern times this is probably the most misused word. The first part of the word, homo comes from the masculine
Latin noun homo hominis (a third declension noun for any latin scholars) and it translates as
man or human being. Phobia comes from the Greek word phobós which translates as fear or morbid fear. So when combined they form the word homophobic which is and adjective for one who is afraid of
man and a non homophobe, one who fears
man, or homophobia, the fear of
man. There is nothing about homosexuality in homophobia. A better word may be homosexaphobic.
Homophobic is used wrong because very few
humans are afraid of human beings.
Homophobia is most prevalent in all other species who have become afraid of
humans because of our harmful actuons which result in their habitat loss and eventual death.
