You say that you are following the regulative principles, so if you are following the regulative principles, why you will not cooperate? If by following the regulative principles you do not become devotees, and you can not appreciate other devotees, then what is the use of these regulative principles? If you are actually chanting regularly 16 rounds, holding sankirtana daily, reading our books as much as possible, like that, then I think you will feel that such program of living separately, away from our Krishna consciousness program is a great mistake.
