Actually, I knew Roger had made a movie or two. I used his name for the instant recognition and the high respect his critical skills are held in (and I hoped no-one else would remember the movies). But if he hadn't made them, would his criticisms be invalid? Trolls are a problem both for the hurt they do to the individual target, but even more for the flame wars they ignite. However, let us not let fear of trolls be the worse threat. I would rather not have us walk in the fearful silence of self-censorship. I admit to being personally split here. It is so nice to have a place where artists can congregate and share, sheltered from the harsh world. It is wonderful to have this place where artists just starting out can take their tentative steps in relative safety. Some of us are harsher towards ourselves and our own work, however, and hunger for critiques that will help us learn and improve. God...could I alliterate more? Here is my compromise. I will keep my commentary bland when I visit the galleries. But if you come near me in chat, where you are there to defend yourself personally, I will assume a desire to be critiqued.
