Why do hear so much from atheists and so little from agnostics?

Is it that agnostics tend to be low-key or is it that atheists tend to be loud and aggressive? Or is there an educational disparity? I must be frank: I know many well-educated agnostics,but I've yet to meet a professed atheist who did not impress me as fairly under-socialized. I ume others have had different experiences,but that at least has been mine. Do we have any agnostics on R&S? If so,why do we hear so little from them? I would think they would be unusually objective,as compared to either Christians or anti-Christians. Opinions?
