I will try a discussion thread here and see if I am on the correct subject.
The description of this group includes the words social solidarity. I wonder how members of this group will like to define this. I think historically there are many attempts to organize people with a common goal. The nature of these movements seem to be linked very strongly with charismatic individuals or radical political philosophies. Are there ideas that have not been understood and tried before?
The second part is: how can one create social solidarity on for large groups without compulsion? It appears to work for some religious groups. I think this is because some people prefer to belong to groups even if they don't agree with everything the group represents. I don't think atheists are very willing to belong to groups.
