Yes, at some point it will. No use kidding ourselves about that.
What will matter is how the initial skirmishes are resolved.
Baltimore, Fergusson burned and looted, Conservative speakers silenced at public universities, assaults by the Left against more conservative groups lawfully rallying and police doing nothing to stop them, events shut down due to threats of Left-Wing violence.
Whole States defying Federal Law, Cities defying Federal Law.
In some ways, it would be preferable that a "citizen militia" arise from the conservative states. This will avoid the onus of having the military be solely responsible for "crushing the left". Better that the traditional-minded Americans handle this themselves...
Yes, and no.
The second some Leftist gets shot, the Left will want our guns, and the war will go hot.
Any pushback has to be done with less obvious equipment, stuff that can be considered improvisational. That doesn't mean be unarmed, because if word of that ever got out, the other side would start busting caps, but any use has to be clearly force justified by equal force, and that will mean someone will likely get shot before anyone from the right produces a weapon. Keep in mind an old tactic is to remove the weapons and claim the shooting was not justified, and that is used from Afghanistan to Compton, whichever way you go, so any shooter who meets with force will have to be secured, along with the evidence (the weapon). That can be tough to do. Just a crowd rush can push someone off a crime scene.
The enemies of freedom are well organized, not just some punks, but coordinated, led, and following a plan, using cell phones, snapchat, and other means to coordinate their actions. All the 'flash mob' larcenies, protests, and lootings are just dress rehearsals for the day they go Major League.
Chances are that under Martial Law no one will be safe--and with the actions of police departments beholden to liberal governments for continued employment, orders will be followed, and Conservatives ("trouble makers" and gun owners) are likely to be first on the list. Citizen Militias will be painted with the same brush they were painted with in the Clinton Administration: as anything from relatively harmless crackpots playing army to domestic terrorists like Tim McVeigh, with special emphasis on the latter after years of SPLC indoctrination at the highest levels of our government's Law Enforcement Organizations.
I think the solution, instead, is to push local, State, and City governments to do their job and protect the Rights of rally goers who are Conservative, to push Universities to host Conservative speakers and to push back against the muzzling influence of the Leftists however we can, but as non-violently as possible. Identify and negate the efforts of their camera people because you know it will end up on YouTube otherwise.
