Fred - no need for excuses; if anything, I'm pleased to see you willing to call a difference of opinion where you hold it!
It also revealed something else: on reading your first post I returned to wiba and to my surprise, I found my confidence in what I had seen to be a little bit shaken. In other words, I began to doubt my own judgement on what I imagined that I had felt on looking at the site just before I posted. What that shows me is that in such things as taste, it is a very fragile path we tread! Outside or conflicting opinion can really shift our own perceptions of right or wrong. That's a reality that I suppose politicians and social activists have always used, and perhaps the best way to handle these choices is to go with our first impressions, which are then our first impressions and the measure of what we really like or enjoy.
Regarding the Gianfranco Meza agency, I first discovered the site some years ago and they had a larger and possibly more exciting list of shooters. I think I remember Javier Vallhonrat being part of the équipe (remember his much copied mania for figures inside boxes?) but he seems missing now. Parisotto Vay wasn't with them when I found him - he was on the pages of French PHOTO and with the Calypso de Sigaldi agency. What an incestuous world is photography.
Would I want to do it again? I think the truth is that the sensible reply to my own question would be NO! but that the truth would be that I couldn't imagine spending my life doing anything else. That basic paradox is what allows those who exploit photographers to continue to so do, and probably for ever.
