@LiberalLibrarian The same people who quote Bishop Tutu, telling us that staying neutral in situations of injustice is choosing to side with the oppressor, tell us not to talk politics.
But how else can we figure out how to live with each other in peace, harmony, and justice? Charity only ameliorates the effects of injustice; armed rebellion kills people, probably for nothing.
If you want to do anything meaningful about injustice without picking up a gun, you have to talk politics. That's all.
