Well then. My impression of the blog entry, at this point, is that it isn't saying "if someone does X they support rape" in a direct, "you are a terrible person for doing this" way, and is aimed primarily at an audience that would understand that. If not immediately, then with a bit of thought after reading. Rather, the point is more that the behaviors listed contribute to the objectification of women, and this in turn supports a culture that indirectly supports rape. Or directly, in some particular cases. The degree to which that is true of each individual action/belief listed is variable, as is the directness of the support, but I can see how most of them can be connected.
As I said above, I don't particularly get the impression of a "you are a terrible person for doing this" attitude so much as simply observing these are, in fact, happening and (to varying degrees) contributing to the "rape culture", as I believe she worded it in one of the comments. Rather, understanding that it is meant primarily for radical feminists (as she herself describes it and her main readers), it is meant as a compilation of already existing concepts for reference, further discussion, and thought, ideally leading to something constructive in other areas.
The main idea, therefore, is simply revealing problematic behavior. Not condemning, not accusing, but observing and highlighting. Not saying that anyone who does any of it is a rapist, supporter of rapists, or would-be rapist, but someone who is, intentionally or not, supporting a culture that leads to such. That is what I get out of it at the moment, anyway.
That said, I really don't see how it's blaming rape victims.
