Let's say half of the states in America want abortion to remain legal. And half of the states in America think it's literally a crime against humanity and try to pass federal laws to make it illegal. So, the half that want abortion to remain legal decide to secede from the Union, rather than remain under a statist regime that ignores the rights of the states. The other states, determined to preserve the Union at all costs decide that engaging in battle against these states is the only remaining option. Is this war justified? If not, then are you prepared to defend the Confederacy as well?
