This has been a growing question in my mind, after spending much time trying to understand homophobia in order to try to help end it.
One of the problems is that a 'phobia' is a fear, but 'homophobia' is generally understood as a hate. So supposing we do define it as a fear, then what do we have?
Don't you think both parts of this 'fear' definition are really important?
Then, if we think about the 'gay hate' definition, I also find some difficult questions there. I mean there are very obvious parts - being beaten-up because of being gay or being perceived as gay (heterosexuals can also suffer homophobic bullying), or being ostracised (often by people in the name of their religion).
But there are also things that are said, that to one person may be classed as 'homophobia' and to another one (I offer myself as an example) could be taken as a compliment. Some illustrations:
So we have words which are sent with homophobic intent that may or may not be received as homophobic bullying; and we have words which could be logically statements of fact which may be received as homophobic bullying; and we have ill-considered statements of no homophobic intent whatsoever that may be received as homophobic bullying.
Of course, we can say things like "intention is important" and "how they are received may depend on whether someone is comfortable with their sexuality", but I've seen that people are being disciplined in schools as homophobic bullies for saying "That's so gay!". (I think that is as bad as allowing homophobic bullying.)
OK, do you see where I'm coming from? Whatever point of view you personally have about what constitutes homophobia and what doesn't, I guess you can see that it's quite difficult to arrive at a consensus. Without understanding (maybe reaching a consensus about) what is homophobia, it's quite difficult deal with it in the right way.
