Common meaning:

Non-white group that includes Black, Indigenous and people of color.

Hidden meaning of the Equity religion: 

Three groups that have agreed to come together in solidarity to fight Western values.

Discussion:

The Equityists believe that people in Black, Indigenous and people of color groups have experienced generations of oppression that must be addressed.

Equity was having difficulty getting traction in Western society until some of the leaders figured out a way to use the concept of intersectionality to bring groups with different grievances together. The various minority groups formed themselves into a coalition of convenience. We see this with the BIPOC alliance, where groups that greatly disliked each other have been unified under the banner of those oppressed by white supremacy. 

To be clear, the enemy that this coalition has identified is not a fringe group, but all of white society. All western values, including humanity, compassion, curiosity, grace, thoughtfulness, openness, punctuality and hard work, must be destroyed.

Clearly this virus of a religion must be stopped.
