Definitely my work is political in the deep structure. I am asking people to participate in creative processes as collaborators in the work. This is different from the political meaning of creating a master work to be appreciated. I think you re right in that making a work that functions as a kind of invitation rather than a confrontation is a radical approach, and really shifts our understanding of personal responsibility and perception the deep structure. Though I can imagine sometimes there would actually be a resistance on the part of an audience toward participating to follow the invitation.
Audiences can be very responsive to participation.
However, I have certainly encountered resistance or shyness in a particular audience. I am not quick to judge this, though. Very often the experience may be deeper than I could imagine even if a response is quiet or short. Audiences seem more willing now to participate than 20 or 30 years ago. It is important to me to have community with my work and the work of others.
