I'm well-aware of Megan Meier, as I am of people who killed themselves after being bullied at my school. If they can't handle a little bullying, or come up with a constructive way of ending it - here's an idea, if you're being teased on MySpace, stop going to MySpace - then they're obviously weak-minded. Unless they have some sort of medical disorder such as clinical depression, in which case their families should notice t and take them to a doctor.
Which wiki says her family was doing.
The idea of 'if you're being teased in venue x, stop going to venue x' makes some sense in theory, but doesn't always work that well in practice. Especially if the logical endpoint of withdrawing from everywhere you encounter teasing is to become a hermit and hide in your room.
The idea of seeing a doctor in order to prevent suicides from happening is a good one in theory too, but every single person I've known personally that committed suicide were involved with with seeing doctors and/or mental health professionals, so it doesn't always work so well in practice.
