LOVE is Social Justice in Human Systems

Pope Francis has been emphatic about this - that the most important subject in life is love. I thought all the while it is one of those platitudes and inspiring quote only but realized recently the practical and realistic implications of this to the chaos of political-economy when I encountered this tweet:

Indeed, Social Justice or the struggle for Social Justice is the noble cause of Love in practice. Social Justice pervades our individual and social lives. Our levels of commitment to it may vary in degrees from altruistic small acts of kindness, to socio-spiritual efforts to social reforms to social revolutions. Love, however, is the thread that connects these.
