I do not believe PUA is rape. I do not believe that "acting confident and suppressing nervousness is rape". I do believe that sex coerced without the threat of sexual violence can still "count" as rape.

So do I. There are all sorts of coercion that are on the order of potency as physical violence or sometimes even worse which do constitute rape. (I actually drafted a reply to anonymous along these lines but the details were starting to seem distracting.)
