Though I can understand your disappointment at being treated unfairly, it should be kept in mind that a rescue's priority/focus should be on the dogs in their care. There are a lot of rescues out there doing a lot of good for a lot of dogs, saving lives, giving a second chance to dogs who may not otherwise get one and that is what rescue is about. Absolutely, not all rescues will meet everyone's perception of how a rescue 'should' operate, not all will be a good 'fit' for every volunteer, that is a reality.
