So is the Corsair-SCRA split the reason why you are so opposed to the fact that the SCRA's main ZoI is in the Omega systems? Because if it is, I call bias and the SCRA ID should be handled without any of your input.
All ideologies, reasoning and justifications aside, it's not like it is unseen or even uncommon in history for different groups to go to war over absolutely ridiculous excuses. Here we have two parties, the Corsairs who are well known for being an anarchistic paradise of "might makes right" pirates, and the SCRA who have drawn a great part of their membership from that exact group. One day they decide to up the ante a bit, they find the most ridiculous reason they can find to justify taking whatever toys they can scavenge and going off to another system from which they can wage war on everyone - now including the Corsairs.
I honestly see no issue here, and you as a history teacher shouldn't either. Provided you're not biased on the subject that is.
