I don't imagine anything about Martin, I know him (W2S), he knows me (BNS). His ancestry were Thames watermen, making the family he married into quite appropriate.
There are lessons to be learned about going overboard in the French and Russian Revolutions in class hatred. Not only did the revolutionaries waste their time on harmless prats while allowing the really dangerous politicians free rein, what it actually did was allow even more pompous middle-class prats to imagine they were better men.
I talked a while back about Tony Benn's five questions to someone with power. The thing to remember is that at the top, the only way is down, and they say rags to rags in three generations: many of the toffs are prats who'll not survive because they're not real. Your proper target should be those who abuse power, and you'll find as many of working class origins in that list as you will middle and upper class. A real person won't fall into that trap.
And it's real people we are for, true to themselves, and class hasn't got anything to do with it. It's abuse of class which has, and the two are as different as chalk and cheese. Yes, there is more responsibility to be demanded of an upper-class abuser, but don't let the pipsqeaks off the hook either!
