The pathological wealth cult, their corporations, banks and puppet politicians use patriotism to dupe the majority into bombing each others' homes, infrastructure and families to death ... for profit.
When they say patriotism, they mean nationalist patriotism - an accident of geography, past conquests and media driven cloning - that requires no positive attributes for membership.
It's ironic that the same multi-billionaires now move their cash freely from one continent to another (via the Cayman Islands) and own shares in multinational corporations.
A more mature version of patriotism is fellow feeling for everyone that aspires for and works towards the betterment of society for all people in all continents.
We need an anthem and a flag ...
