It is essential to value all citizens as an equal and loved part of the nation, of the national family, and for immigration to become a grown-up discussion based both in heart and logic. Realistically, any buffer can only take so much addition before it cannot buffer the changes and remain stable. And buffers are all or nothing, they are either within boundaries or they are not, and so change is sudden and challenging to reverse. Thus a social haven, a peaceful society, can only remain a haven while its social buffers remain within their buffer range. Any chemist or biologist can tell you that this is true; as it is in the body, it is in society. So while we must always remain big hearted we need to let both heart and logic guide us as a national family and keep us united. We can accept new family members to our nation within realistic boundaries of what we can cope with and we can donate aid to countries in need as much as we are able to in order to increase the quality of life for people globally. Only by remaining united can we be strong and rescue others in various ways. We can't become a nation that requires rescue. Thus, we can't take everyone and we can't ignore their suffering. So an adult way forwards will emerge as we take a psychologically mature view - heart and logic combined.. a new "heartology." It makes a path we can all be proud of even when it involves tough choices, as it inevitably will.
