I recently flew from Houston to Chicago to visit family. Some of the family I spent time with I like. Others I could take or leave.
We should be free to define family as we wish. For example, little is more mean and intrusive than telling people who they may or may not marry. Life is short and it is rotten to deny people the relationships that they want and hope for.
Also, we may feel we have friends we value more than people who by conventional definition are seen as family. Or we may feel that a requirement for a close family relationship is that the family member in question be someone we would want as a friend.
None of this has anything do to with treating family and all people with basic civility and respect. These are universal obligations.
Values we associate with family such as love and loyalty can become selfishness when not open to others. Family should be defined as broadly as possible.
Individuals have the right to decide who they wish to include in their own idea of family.
