1. If it is "man's" responsibility to stop raping, and not "people's" responsibility to stop raping, then we can conclude all men can rape, and we must remind them to stop it. Plus, it says only men rape.

2. Only men, as a group, would ever be allowed to be labeled in such a way in polite society. Compare "Men Can Stop Rape" to "Black people can stop smoking crack" "Women can stop false rape accusations" "Schoolteachers can stop raping their students" "Latinos can stop illegally crossing the border" "Palestinians can stop blowing up city buses" and this becomes clear.

Conclusion: ANY person or organization saying "men can stop rape" is bigoted, and should be called such, repeatedly.
