It'd be damned boring if everyone thought the same thing, after all.

I rather think that absent wars and insurrections, the pace of change IS slow; as to the form that that change shd take, I think it supportable in canon to argue either way, although it doesn't do to be too dug-in abt this sort of thing, really. It's these differing views and tastes and what not that make fandom interesting, isn't it - although we've strayed rather far here from where we began.
