It will come down to that, as the Union thugs (the NEW "Socialist Workers Party" under the names SEIU, AFSCME, UAW, etc., etc.) will find that the 2nd Amendment was put there for a reason, which is self-defense and protecting Freedom, even as the Union Police Departments and the Federal Government's own military (the FBI, ICE, etc.) refuse to act (such as in Wisconsin).
All I will say is, this will all blow back in the trouble makers faces.
