If a man were the victim of a crime or was violated to such a degree I would expect them to report it to the police. I honestly can't think of a good reason not to, unless of course they were extremely ashamed and didn't want to share the experience at the expense of their pride. But I do believe they have a moral obligation to report the crime yes.God forbid but if you were held down and overpowered by another man and he raped you, would you report it straight away? Can you think of any reasons, hypothetically, why you might not want to? At least, not as soon as it happened?
What is your counter argument exactly?
