Male abuse victims come from all sorts of emotional places and experiences- you need something general as to not exclude anybody.
Universal messages are a good idea, but I think more specific messages might make a good supplement. I think there isn't enough attention being drawn to common myths about sexual abuse: all abusers are males, male on male sex abuse is gay sex, sex abuse is a "private lesson" - an initiation into adulthood, etc.
AIDS is a good example of what I'm trying to say.
Consider these AIDS statistics.http://aids.gov/hiv-aids-basics/hiv-aids-101/statistics/
Gay & bisexual men of all races are the most severely affected by HIV.
While blacks represent approximately 14% of the U.S. population, they accounted for almost half (46%) of people living with HIV in the U.S.
Now consider this.
1 in 5 living with HIV are unaware of their infection.
I suspect one reason for the 1 in 5 is that myths persist about how HIV is spread. A lot of younger gay males think AIDS is easily manageable (it's not). AIDS is often seen as something that only happens to white people (not true) or drug addicts (also not true) or gay men (ditto). Research suggests oral sex isn't safe. How many people know that?
A young gay male who makes risky sexual choices, an IV drug user who shares needles, and a woman who can't say no to her husband have unique circumstances that should be addressed, which is why I think campaigns need to target these groups specifically. It's true that AIDS can happen to anyone, but highlighting different populations affected by HIV/AIDS will not only support that reality but also address the unique circumstances in each population.
I think that campaigns targeting male survivors of abuse also need a variety of messages. There isn't enough said about survivors of adult sexual abuse, for example. They must really feel left out.
