First they came for the Muslims, but I was not a Muslim, so I said nothing. Then they came for the Hindus, but I was not a Hindu, so I did nothing. Then came the Mormons, but I was not a Mormon. And then they came for the Catholics, but I was not a Catholic, so I did little. Then when they came for the Protestants, there was no one left to stand up for me.
"Those who give up essential liberty, to preserve a little temporary safety, deserve neither liberty nor safety." -Benjamin Franklin
