Common meaning:

Harmony of opinions on a particular matter. In a negotiation, both sides may need to give some ground in order to achieve agreement.

Hidden meaning of the Equity religion: 

Agreeing with anything but Equity beliefs is considered a betrayal.

Discussion:

The adherents of Equity cannot give any ground or agree with any other ideas because that would be upholding what is evil. 

As a radical religious faith, it is looking to convert those who have other opinions, and if that is not possible, then to destroy the argument, and potentially the life of the person they are having a disagreement with. 

Some people think Equity is a political thing, but it is a religious thing. It  is currently making its home on the political left, but it just as easily could have come from the political right. Others think this is just being spread by crazy and evil people, but again it is religious and everything that is done fits within the doctrines of this radical virus faith.

Since one of the core beliefs of Equity is that everything in the Western world is oppressive, it makes total sense from their perspective to never attempt any compromise with those who are part of this evil system. From their perspective, agreement with anything others say is a betrayal of Equity beliefs and it makes them complicit in harming others.
