You most likely find homophobia origins in religious texts.. and funny enough some churches/religions ban it outright.. although their 'brethren' obviously haven't heard about that yet. ?
If we're going to be all treated like human beings, irrespective of orientation, one has to be able to roll with what it takes to be 'different'. We all have to go through this in our lives... being gay doesn't require any more special attention than being straight, or just being a weirdo.
Jokes, quirks.. etc.. are par for the course.. time to toughen up and stop crying, otherwise they'll 'ride' you.
