Rape - why?

[thir]

I think both philosophy and politics and quite possibly religion come in here in this theme, so I wanted to ask what people here think of this kind of thinking:

Look at this picture:

Is she asking for it, or is it a valid political statement?

Is it really all about power?

Are men really raping women because they hate women?

Why do men rape men in prison?

Is it true that sex plays a secondary or no role in this?

They say most rape is done by people known to the victim. How does that fit in?

It is said that the social barrier to rape is much lower than the social barrier to murder. Is this true? And if so, why??

In the UK so few cases get to court that rape in many areas is de facto a free lunch. why?

Any thoughts??
