"When people are rude, they deserve rudeness back." Right. We should be rude to rude people in order to teach them that rudeness is wrong. "Ummmmmmm NO" I understand people's frustration but if it is a "Gallery," since when do visitors to an art gallery have to say how they would have done something differently? I don't like a lot of Picasso's work. Do I have to explain how I would paint it before I have a right to say that? If that's what you want, then you need to ban all non gallery contributors from the galleries. Incest anyone?
