HELP! KILLJOYS NEEDED!

doing a project at school on self harm. basically, using the time to have a rant about prejudices towards people who are different. have used GW as an example of the guy you think will self harm but actually tries to get teenagers to realise that t doesn't have to be that way. what else can i say to get people who think that self harm comes with a tube of eyeliner to understand that it is not something to be sneered at and to take the piss out of people for.
