If you are in this forum, I'm going to assume you know all about how feminism redefines rape as pretty much any sexual event (even consentual) when the woman feels like slandering the guy.

It harms the interests of parties concerned about preventing legitimate rape.

On the most simple and obvious level, this is a threat to that interest because throwing the "rape" word around the way feminists do (and the way feminist propaganda implicitly encourages women to do) is like crying wolf.

But it goes further than that. For example in this thread (on /changemyview, a debate forum), OP makes reference to a case where a lawyer used feminist propaganda as a defense for real rapists in legal litigation, and won. (http://www.reddit.com/r/changemyview/comments/1dxsta/the_current_movement_of_feminism_actually_hinders/)

One of the biggest threats to Men's Rights is culture's brainwashing by feminism. Exposing feminism to be the ignorant and predatory social problem that it is (rather than something positive and empowering), helps us get taken more seriously.

The way to do this is to appeal to as many special interest groups as possible, beyond Men's Rights. One of those is groups working with and helping the victims of real sexual abuse.

It is particularly a good group to focus on, because it is something feminists claim to align themselves with. By turning those groups against them, it weakens feminism.

I invite everybody to expand on my idea, communicate it in a more thorough and comprehensive way than I am capable of, and make it actionable.
