As an example the WE Party (A United World Social Network) would be a great positive social networking site. People can talk about what they do have in common, rather than what we don't have in common, and how we can move forward together. This goes for all religions and political views of only like minds.
It's a social networkiing site with a collective consciousness of WE.
Through this collective consciousness, we will come up with non-violent solutions to problems.
