Unfortunately I don't think the group of 'just want to secede' is "much larger" than those willing to commit civil rights violations after years of practical experience living in the south. The people saying it in the context of the blue states doing it mostly realize it won't work, and the amount of civil rights violations either way skyrocket in the process.
