1. A number of people in the US find sex to be degrading and harmful, at least on a subconscious level, while most reasonable people would only apply those epithets to a small subset of sexual activity.
2. People who harbor unhealthy beliefs (such as those described in 1) have a tendency to behave in suboptimal ways according to those beliefs, often with results that confirm them. An example of this is the misogynist/misandrist; people who believe that all members of the opposite sex tend to repel quality partners and have a very limited range of experience, and those negative experiences reinforce their beliefs.
3. Men who fit into the stereotypical "alpha" category strive to humiliate and damage women; thus, sex with them is, in fact, harmful and degrading.
4. Ergo, according to (2), women brought up with the attitude described in (1) are likely to be sexually attracted to the sorts of men described in (3).
I don't see anything vague here.
