Wars are what happens when Shunning gets too far out of hand

 Wars can be looked upon as one group shunning another group until violence ensues and many people are dying. One can look upon the Ukraine war where Putin has one point of view (or religion) and Ukraine has another point of view (or religion).

For example, Putin's religion would be: the Communism of the old Soviet Union (if one is realistic about all this). The next component of Putin's religion would be: The historical Russian Empire of the Czars especially Peter the Great and Ivan the Terrible.

So, thinking about shunning in this case you can see where it all can go and get so out of hand that thousands or millions of people are dying in such conflicts.

But, it all begins with a form of Shunning of people who have a different point of view.
