Can someone please explain what "rape culture" is to me? I've heard this term lately and it doesn't make sense to me. It conjures up ideas of some subculture of rapists in America. Like we could find aspects of Chinese culture, Indian culture and Native American culture.

I'm pretty naive about this whole thing, but are there really groups of guys sitting around in a basement saying, "Well, it's 5 pm. Rapin' time."
