In my research for the presentation at John Bentley School I found a rather interesting and full definition of homophobia by the crown prosecution service.
Homophobia is:
A fear of or a dislike directed towards lesbian, gay or bisexual people, or a fear of or dislike directed towards their perceived lifestyle, culture or characteristics, whether or not any specific lesbian, gay or bisexual person has that lifestyle or characteristic.
The dislike does not have to be as severe as hatred. It is enough that people do something or abstain from doing something because they do not like lesbian, gay or bisexual people.
I really rather like this definition.
