I expect people are downvoting without explanation because, frankly, this reads like sufficiently obvious sexism it’s difficult to believe that the author hasn’t noticed. Assuming you want an actual explanation of what’s wrong with this post, I think there are two main parts:
Epistemically speaking you are making very confident sweeping generalizations about something which is at best a tentative evopsych theory and at worst utter nonsense.
Socially, this is incredibly dehumanizing and othering. Women are not alien intelligences. We think the same way you do. Ferreting out the fundamental intentions of men works the exact same way as ferreting out the fundamental intentions of women.
Ignoring questions like tone or whether this post belongs on Less Wrong, this specifically is obviously unethical. Do not start a club to hit on undergrads who join it. Do not hit on your students. There is a power differential and you are on the wrong side of it.
