Is this breeder trustworthy?

I have been emailing with a breeder back and forth for a week or two now. Recently I sent a long list of questions about their dogs health, temperament, and living condition, etc., which I thought were perfectly reasonable questions to ask. Today I find out that the breeder refuses to answer any of my questions because they are an "insult to them as a reputable breeder". Was I actually in the wrong, because I was shocked when I got the email.
