It's up to you what you focus on. I feel people have the right to talk about whatever they wish. It's not for others to say one way or the other. I would say it is the criticisms of others that leads other's to complaining in the first place. You want to go in holding others up, then do so by not telling others how this of that place should be run. If your in a depression room, then expect people to be depressed. If your in a bipolar room, then expect it to go either way. You choose what you say, but don't be choosing it for others.
