This is ridiculous, I mean, wholly ridiculous. It never did any child any harm to have something that was a tiny bit above them anyway, and I claim that anyone who can follow Doctor Who can follow absolutely anything.
You can get really left of centre influences in mainstream pop. Michael Jackson and Prince are some of the most progressive artists ever if you actually dissect their songs there's some crazy stuff going on.
We all have these tendencies in us that could go this way or that. I think that's the real key in writing. To look at a character without judgment.
