Now it's whether men can magically turn into women, whether people can be forced to take a wide variety of vaccines, whether people can be allowed to make a living, assemble, worship in churches, black power, crime, eliminating police, socialism --- I'm sure there are more.
Yeah, we're WORSE than in 1859, so secession may well happen. Remember, people: it happens incredibly fast or it doesn't happen at all. Days, not weeks. For example, Yeltsin climbs on the tank, and Poof -- no more Soviet Union. The American union started breaking up the day after Lincoln's election.
