So when the church owned black slaved not 200 years ago in the U.S. we should have been radically Christian in your opinion and just told those black slaves to shut up and realize they are just playing the victim.  

Great job.

I think you do not know what Christian means and actually need to read the Gospels which provoke all believers to stand up against hypocritical teachings of religious leaders.  Do what is right and treat all the same because there is no authentic unity without authentic justice for all.  

That is why Jesus tells us that above all else Love God and then love your neighbor no matter who he or she is and never treat others differently than you wish to be treated yourself.
