I don't know if this is any good but I hope it annoys the fuck out of them...

Dear MomDadNanna,
I don't think you realised just how many people you'd be likely to piss off with your laughably under-informed reaction to the article on Silbury Hill which you saw fit to judge from your lofty standpoint accross the pond.
Being British myself and having a keen interest in the Neolithic of Western Europe (that's from around 5000BC to around 2500BC) I find it hard to imagine anyone condoning the willful destruction or damage of one of that culture's most important sites.
Silbury hill is 5000 years old. It has been known about for slighlty longer than 500 years. You buffoons. I know you only have 500 years of history in your blinkered land but over here in the old world we have a few more.
Now the 'Ed' to whom you addressed your article knows his shit, to use the vernacular, as do I and many of my colleagues. You, it would appear, do not.
It's axactly the reactionary bullshit you were spouting that leads to libel cases against people like you. Believe me, we know the importance of the truth over here. We also like the word 'allegedly'.
So read some books ('books? what they?' you cry) do some research. Learn some facts. Say something constructive. Or F**k off.

All Love,

Spaceship Mark.

PS Why not elect a president who knows to take the lens caps of binoculars next time?
