Doctor Who: in which the Doctor was too polite to... wait, what? Too polite?

I encountered an interpretation of the tenth Doctor/Rose relationship that I found baffling. Not just that it's not my personal interpretation, because that's one of those subjective things and whatnot, but a viewpoint for which I cannot see any possible canonical evidence and do see a preponderance of evidence that disproves it.

( the interpretation of D/R that's confusing me )

I have three main categories of evidence which I will show you to further illustrate why I do not understand this point of view at all.

( Exhibit A. Tennant's Acting (not dial-up friendly) spoilers through 4x13 - 'Journey's End' )

( Exhibit B. The Text )

( Exhibit C. The Doctor's Personality )

( in conclusion )

But that only adds to my personal confusion in the matter. I can understand not liking Doctor/Rose -- I dislike John/Aeryn (Farscape), which makes me part of, like, the smallest fandom minority ever. I can understand thinking that their relationship is unhealthy -- again, I point to my feelings on J/A or Sam/Jack (Stargate: SG-1). I can understand thinking that they can't work out in the long run -- see my feelings on Buffy and any/all of her canon boyfriends (Buffy the Vampire Slayer). I can understand wishing that they weren't canon -- that's precisely how I feel about Harry/Ginny (Harry Potter). I can understand lots of things.

This, however, I just don't understand.
