Throughout the history of mankind there have been murderers and tyrants; and while it may seem momentarily that they have the upper hand, they have always fallen. Always.
My method is conversion, not coercion, it is self-suffering, not the suffering of the tyrant. I know that method to be infallible.
Non-cooperation with tyrants is a duty.
Remember that all through history the way of truth and love has always won. There have been tyrants and murderers and for a time they seem invincible but in the end, they always fall -- think of it, ALWAYS.
