Common meaning:

Learn something so you are no longer ignorant.

Hidden meaning of the Equity religion: 

Because you are part of a dominant group, you are a worthless human.

Discussion:

If an Equity believer is talking with an unbeliever who refuses to accept the true faith, they should be told to go and educate themselves. 

One of the liberal ideas that was celebrated during the Enlightenment period was the importance of educating yourself. Each person was encouraged to question whatever they were told by the authorities of the time, and use their own reason to figure out what was true and right. Equity believers use the phrase “educate yourself” to attack people for not believing in the authority of Equity doctrine. You need to change your thinking to come in line with what the religion says.

What an Equity believer is actually saying when they use the “educate yourself” phrase, is that the person they are talking to is a worthless human being. As a member of an oppressive group, they are not even worth the breath to talk with and they need to discover for themselves why they are a sinner.

Believing that other groups of people are worthless humans is beyond problematic.
