One reason I used to be a Protestant Christian was to protest injustice and other nonsense both outside and inside the Church.
These Jewish and Catholic protesters are, in that sense, good protestants:
Restoring Faith in Faith (E.J. Dionne)
This is what I consider the heart of “true” Christianity … or at least closer to the actual disruptive teachings and radical life of Jesus of Nazareth–minus the theology.
(I think it’s fair and wise for seculars to call attention to the good acts of believers)
