I'm very late on this, but I'll unequivocally declare that I support black love--although I confess the term may have a different meaning for different people. I define it as love for our people as well as our families and history, music, culture, etc.
That written, I believe loving our black family members, friends, history, music, etc., doesn't preclude us from loving our nonblack brothers and sisters as well and what they bring to the table.
I do believe we have all been created in God's image, which means we are all siblings regardless of subjective racial demarcations. Black love is fine but I don't stop there. I try to practice love and respect for all of my brothers and sisters of all races.
