I think most people miss the point of what is truly implied by the statement “an injustice anywhere is a threat to justice everywhere.” I believe that most people miss the duty that is presupposed by this statement that we all have to rout out injustice, exploitation, and oppression from whence it emerges, wherever and whenever. Whether that be from KKK members, racist presidents, teachers, or friends. When our homeboys are being sexist, when our fellow revolutionaries are screaming and fighting to be treated and valued as human beings and are dehumanizing women. To the people we pass on the streets whatever the case may be.
The statement means that I can not experience liberation if someone else is being oppressed or exploited. Our system, as it exists, cannot permit liberation, will not permit liberation, because it requires exploitation and oppression to sustain its existence. To achieve liberation, we have to achieve an entire psychic change, experience a complete overhauling of our collective system of values, completely revolutionize our entire economic structure, and most important our own personal perceptions about ourselves each other and our world must be radically altered and compelled to evolve.
Only then, when injustice in all of its ugly forms is shunned and rebuked, by everyone, will we ever begin to achieve liberation. This is what I understand this statement to mean.
