I agree to a certain extent. For example, it is infuriating that so many public awareness campaigns focus not just on women as victims, but that women are at least partly culpable if they have been drinking, taking drugs, get in an unlicensed cab, etc. In my view, it would be more beneficial to have campaigns that aren't just focussed on rape but more for people to "look out for their friends," who could be at risk of all sorts of things from assault to alcohol poisoning.
Campaigns specifically about rape should target perpetrators/potential perpetrators (and that's blokes,) but frankly, I don't think those make any difference. Men who rape (whether the victims are men, women or children) don't believe they are doing anything that wrong, so won't believe the posters or adverts are anything to do with them.
However, it's important to realise that misogyny is inherent within the act of rape. Straight and gay male and transexual victims are often viewed as "proxy women," (i.e. humans of less value) and raped for pretty well the same reasons women are raped. It's exerting power and control over a person the perpetrator sees as of less value, whose wishes are secondary to their own and using the sex act as a means of exerting this (often with other things like violence and demeaning language.)
For that reason, it IS important to set rape within the context of a patriarchal society that values some people less than others.
