GREENBELT campaigner Janet Thomas is "saddened" her group has been accused of 'nimbyism' at a critical point in its fight.
She and other Brockworth villagers have been working hard for months to oppose plans for a 1,500 home estate next to the A417.
They have stepped up their efforts this week and pledged to attend three different council meetings to challenge councillors face-to-face over the issue.
Janet started Save Brockworth Green Belt in the summer after the proposals were revealed by Hunter Page Planning.
Mrs Thomas said: "The group have genuine concerns and issues regarding the possible large scale development of the land. Sceptics we may be, not Nimbies."
Nimby is an acronym for "not in my back yard" and is generally used to deride campaigners.
Mrs Thomas said: "I understand why people have said that but it is annoying and quite disheartening as we are working so hard to try and protect the beautiful countryside we have in Brockworth."
The group has collected more than 1,000 signatures in a hard copy petition against the plans and its e-petition closed yesterday with 250 signatures.
Group members are questioning the idea of the draft Joint Core Strategy, which they say opened the door for the Hunter Page plans by listing the A417 land as a possible development site.
They were at Cheltenham Borough Council on Monday and are due at Gloucester City Council's meeting tonight and Tewkesbury Borough Council's meeting on Monday.
