This discussion is highly likely to go around in circles forever in a day, and I'd like to think that we could work toward something approaching a consensus on this issue but I doubt very much that's going to happen on a mailing list. There is too much room for repetition on a mailing list. Why not use a better resource to conduct such debate, a wiki?
There is now a page on meta dedicated to outlining the desirability of end-user image suppression: http://meta.wikimedia.org/wiki/Desirability_of_end- user_image_suppression
To help work toward some kind of consensus the issues surrounding this topic are split into four main areas:
1. the implications of implemention http://meta.wikimedia.org/wiki/End-user_image_suppression 2. the identification of categories that would be included as part of implementation http://meta.wikimedia.org/wiki/Potentially_offensive_images 3. the useful categorising of images http://en.wikipedia.org/wiki/Wikipedia:Descriptive_image_tagging 4. and discussion about whether it's all desirable http://meta.wikimedia.org/wiki/Desirability_of_end- user_image_suppression
Feel free to join in the progressive wiki-way instead of the circular mailing-list-way. :)
