I really think we would do well to remember that the large majoirty of people in this country, whilst wishing no harm to our heritage, couldn't give a toss about the finer points of an ancient, forgotten religion practised by long dead culturally alien people.
The idea of maintaining a bronze age 'ritual landscape' to 99% of people comes way down on a lits of priorities.
The Rudston Monolith is (I strongly suspect) being used by nimbys who couldn't really give two hoots about the 'ritual landscape' but just don't want a wind turbine in their area for reasons most probably to do with money.
Cynical? Yes probably.
