All good points. I guess the big issue is that Donna didn't appear to consent to what the Doctor did, and that - I think - is the real issue that remains unresolved. What would Donna have chosen had she been able to choose? And in light of the issues being brought up these days, it's a topic that needs revisiting. That is, the Doctor's habit of not respecting that his/her companions have a right to choose for themselves so long as their choices do not infringe on another's rights. (It's a more complicated issue than I have time for. Especially since I'm on a quest to improve my life.)
