I really think it's a small but vocal group of quilt police. They think there is only one proper way to do something, and it's their way. When I run into someone like this, I just smile, nod and think to myself that it takes all kinds, then just ignore whatever they've said. It would be great if everyone would just play nice, but that's not the way the world works. You can't change them, but you do have control of how their words affect you. If you can't ignore them, then avoid them! Sounds like you made the right decision by leaving that guild. Toronto is a big place, is there another guild you could try?
