Definition of family to me is linked kinship, either by blood, common interests or geniune inclusiveness.
Fictive kin is very much included in my definition of family. Black people collectively are included in my definition of fictive kin; however, only in regards to how I see a group I am part of as family. I genuinely wish good will towards all Black people. Yet my immediate concept of family only includes my blood relations and those people who have cooperative relationships with me or my blood kin.
