Yes, very strong message. Slavery comes in many forms, including "self oppression" often influenced by others, or forced circumstance which can be as miserable as any form. I wonder will either ever be resolved. There's few questions concerning reasons behind the enslaver, but self oppression can be more controlled. Martin Luther King was a great man who thought beyond money, and power with passiveness. Anyone encouraging violence, or control, is surely acting through selfish motivation and should be questioned.
Thought provoking photo, & words Mr. Phil. Thanks for sharing.
