Anne, absolutely with you on this and I am in the same camp as you. As with any "interest group" you will get the fanatics, amusingly, the Ricardian variety seem to be pictured among some as wild-haired, tweed wearing matrons with a faint whiff of mothballs and cat pee. I do think that the vast majority of "Ricardians" believe that Richard was a "flawed" human being....after all, who of us isn't?
The Richard III Society is very much a scholarly institution which promotes research into the life and times of the man himself and it is open to anyone to join ( and no, I am not a recruitment officer :-) ).
That seems pretty rational to me Eric, after all, if we all thought that Richard was whiter than white or blacker than black, there would be very little if any, discussion at all.
