My meta explanation is consistent with every quote you came up with - and the rest of the S3 scenes involving the temporal cold war, character motivations, etc.
As for the rest, your post is just repeating previous ones - to which I already answered - plus one-two hand-wavings more. Really, responding in detail again would have no point; you would just keep repeating yourself.
Obvious unpleasentness is obvious.
On your part.
