You don't speak for Christianity. Many support Jesus' commandment to support the poor, help the sick, heal the sick and that we are judged by our charitable actions. Jesus was an advocate for social justice. The prodigal son and tax collector are examples where Jesus showed that even when they acted wrongly but were forgiven, transformed and rewarded. Maybe, by following God's will (Love) will lead you to follow Jesus rather than your will to deny charity to everyone.
