Before I inevitably analyse the concept of female Doctors...
Moffat's version of Doctor Who in particular, involves heavy sociological topics. He does, however, have a habit of constructing his allegories so overtly subtle as to appear elitist to the, who I'm afraid is only a fraction of viewers, who end up noticing them at all.
Whether you are interested in the current show's sociological side or not, it is undoubtedly a large part of the current show, so I must politely ask everyone here to allow discussion of it on a board with "Doctor Who" in its name, instead of attempting to halt it via social pressure.
The casting of the next lead actor, with it's various aspects involved, seems to be the actual main topic of the thread, so that's what I'd like to be able to discuss in a while, at peace.
I hope my civilisedness isn't causing too much harm.
