William,

"Pity the unhappy souls..."

Who is less happy, the victim of injustice or the the professed follower of Jesus who is failing to follow His example of one-to-one ministry that actually relieves the suffering caused by injustice?  

One of the most pitiful scenes I have ever witnessed was seeing long-faced, unhappy Christians going to help someone in need who was much happier than them. The Christians would tell you with conviction that they had "the truth" and you should be following their teaching, but their demeanor could have left you thinking they were instead delivering the news that a loved one had died. In contrast, God-loving believers relieved my times of suffering by reaching into my darkness and brightening my life with the joy of their relationship with God. So, if I have a choice between railing against a perceived issue of political injustice or ministering to an individual, I'm going to focus on the person.
