Having worked with Brat for many years, have never found them either rude or uninterested in a legitimate potential home, and knowing their expectations are not unusual, it is rather important you state what your conflicts were, because honestly, most basenji rescues, owners, and breeders probably expect the same. Easier to be upfront about what you think the right way is rather than waste people's time trying to find you a dog when you may not agree with their ideas on how to best care for their basenjis also.
As for the question being "unwarrantedly, inherently suspicious"... I'd say your response is paranoid. The question was a simply one, trying to suggest other options if you hadn't considered them. Your rude, abrasive and disrespectful responses would put an end to my considering you for help, btw. But others here may be more sympathetic and have leads or a dog once you explain your views.
