Because it's science fiction drama.
I totally agree that there are many would think that the speech was the dog's gonads. It's a fact of life that many, many people see the world through DM goggles.
But I honestly think that a drama about a woman in a coma who goes back in time has no particular responsibility to 'teach', iyswim. It presents characters, we draw our own conclusions.
Actually, I'm sort of in the middle of a bit of existential crisis because of old Mr Hunt.
I found myself thinking, you know what, mate, I don't believe you need to be a bigoted bastard to put what's wrong right. But I find myself attracted to you because you're just bloody sure of which way is up. And I just don't think I know that myself anymore.
And I hate that, because the place I get my moral compass from, that tells me that truth and fairness and justice matter, the only place that makes sense, is the same place that feeds me all this stupid bigotry stuff that part of me wants to applaud because it's sure and certain.
Like madamez said earlier in the thread, if he was real, I'd have wanted to shoot him in the head. But he is real, and I can't shoot him in the head because that's wrong, but I don't bloody well know how to deal with him if I don't shoot him.
