There's a fine line between "protect this as a small rural community" and "preserve this in aspic". I face this dilemma in my village. Had more progressive, pragmatic, decisions been made thirty years ago, we might still have the school, the two pubs, the shop and the post office we have since lost. I wasn't here at the time, but I gather that life was pretty good in the 70s and 80s, however, the assumption that doing nothing changes nothing is sadly misguided, as there are other outside world forces that play their part. We are now just a dormitory settlement with no amenities.
The advice from somebodyelse is good, but there are no easy answers here. I would just stress the "polite fuss" element. Conduct your campaign in a calm and civilised manner. Meet with the Chair and Clerk and sell your ideas to them. Ask them for their support.
