Common meaning:

To form a new concept of something.

Hidden meaning of the Equity religion: 

To consider what things will look like once current institutions are destroyed and everyone believes in the faith of Equity.

Discussion:

The Equity believers think we can get to a better world, where all of the oppressive institutions have been replaced with responsive ones that meet the needs of marginalized people. This can only happen when everyone sees the truth of how terrible our current situation is and can imagine a better world.

When Equity people talk about reimagining something, what they really mean is that they want to destroy it. They are dreaming about what the world will look like when all the current institutions have been destroyed and everyone has been converted to Equity.

What the religion of Equity leads to; what this kind of thinking always leads to, is not a utopia of plenty and happiness but a nightmare of want and violence.

We have tried to create this kind of perfect heaven on earth before and the results have never been pretty.
