A lot of responses to this thread regarding immaturity scream immaturity themselves, but there's nothing wrong with that. Minecraft was designed for all ages so you should expect different view points and responses from various age groups. Older players tend to use younger ones as a scapegoat. You could say that if you're significantly older, you shouldn't scrutinize the stereotypical bad behavior of the younger players. However even that point of view is immature. Just respect all players and either ignore players' immaturity or act as a leader and set an example. Unfortunately, this is the internet, there's a lot of bad impressions out there and very few set good examples.
