The principles are doing just fine. It’s your feeble attempts at warping them to fit the Slavers Rebellion that fail miserably.
Yea, how about that irony, huh?
I don't think it matters if they were drug addicts and wife beaters, the Declaration says a people have a right to leave if they find one form of government not to their liking.
