This is America, where violence is always a means to an end. Attempting to deprive entire masses of people of equal protection under the US constitution will bring the troops, you can bet on it.
"I don't believe you." That'll be your bluff being called. A group will mount a legal referendum, if they win a majority then they'll call for secession. You claim troops will be sent out to oppress the majority of the state. I don't buy it.
Sorry to pop your bubble but they slammed the door on secession, there is no legal avenue to for a state to secede. Also various acts of congress have made it not only legal but the president is duty-bound to put down insurrections by force if necessary.
There was also no legal way for two men to get married, but what are we seeing today.
Something is illegal until it's not. The mentality of our age is different from what existed during the Civil War. You seem to accept that when it comes to all sorts of things, like homosexual marriage, abortion, divorce, Senate elections, living together, etc so why on Earth would you believe that a President would issue a conscription order to unleash American troops on American citizens who no longer wish to be part of America? All around the world we see peaceful secession movements but you think armegeddon is going to be unleashed. You kooky liberals and your death fixations.
Look, us normal people understand why you liberals are willing to unleash mayhem on secessionist - you need us to pay for your society destroying schemes. That's the only reason you want to imprison people into a society that they don't want to be a part of.
