[DiogenesLamp]

The war was over money, but the propaganda was all about slavery after the conscription act law was passed.

I'm trying to grasp your point here, but I can see two ways to interpret it.

1. Conscription = slavery.
2. "Slavery" was used as propaganda tool in an effort to rally popular support after unpopular conscription was imposed.

3. It was a bait and switch. The war started out to “preserve the union”. When the volunteers were made into conscripts only then could the abolitionists have their war to end slavery.
