How do you tell if you are a homophobe?

If you are a homophobe, chances are that you probably already know it on some level. Homophobia has been defined as contempt, prejudice, aversion, hatred or antipathy toward the LGBT community, may be based on irrational fear, and is often related to religious beliefs.

Homophobia is observable in critical and hostile behavior such as discrimination and violence on the basis of sexual orientations that are non-heterosexual.
