Decolonize To Liberate/definitions

What does "decolonize" mean?  No it doesn't mean turning back the clock or sending the Europeans back to Europe. 

There are many definitions and ways to explain it.  I decided to start this page to gather definitions and explanations in an effort to elucidate the meaning of "decolonize"...

Decolonizing is about the culture we’ve allowed to calcify around us. A culture that holds private property as sacrosanct above public welfare. Where an individual’s greatness is put above the community, no matter how much wealth that individual amasses, no matter how much the community suffers. It’s the culture that Christopher Columbus brought with him, and every great man who came after him supported, built up, and used to increase their personal gain at the expense of the meek, thepoor, the brown, black, and every female regardless of color or creed.
