Do the poor want to be politicized though? I think the fact they haven't embraced liberation theology and instead turned to Evangelicalism and Pentecostalism gives us the answer. 

Solidarity with the poor doesn't mean replacing the Gospel with politics though. Jesus told us His kingdom was not of this world. Did He focus on getting the Roman Empire to redistribute wealth or did He encourage His disciples to feed the poor, give drink to the thirsty, clothe the naked, etc.?  Did He tell us to seek first the Kingdom of God and His righteousness or to first seek our material needs?
