The seemingly infinite freedom of speech that the web has given the world is not an entirely good thing.
Along with allowing the repressed and downtrodden to have their view aired, it has given cowards and bullies a platform.
Before, these people did not express their bigoted discrimination widely.
As free speech allows, it did get expressed - but was largely repressed by society. Generally, the bullies crawled back into their hole.
On line - there is no hole. Other than the one anonymous cowards are pouring through, with their vitriolic bile.
If tolerance of cyber bullying grows on-line, it will grow in everyday life.
In the meantime, we have tough new cyber bully laws coming but no organised online police officers.
In some ways, the existing ad hoc scenario is akin to expecting Dad's Army to repel Hitler.
The internet will contribute positively to society this century. But we still need our churches, our sports and interest clubs. Healthy communities will consist of a balance of shrewd use of modern-day technology, and old-fashioned community organisations and groups.
Organisations that encourage human interaction and communication, rather than anonymous sniping from a keyboard.
