Is the BBC being unfair to the Tories?

Apart from one proto-William Hague-like Tory boy, only elderly party members seem to have been interviewed by the BBC after David Cameron’s speech to the Bournemouth conference.

The only TV coverage I’ve seen so far was on the BBC One news yesterday. Nearly all the members who had their ten seconds of fame by giving their opinion of their leader’s speech were even older than I am.

Is the average age of Tory members really so high? Or is this an example of the alleged blatant BBC pinko-liberal bias that causes retired alleged majors (many of whom in reality probably never made it above lance-corporal in the stores at Aldershot) to choke on their muffins?
