You must live behind enemy lines to have such neighbors. It's exactly the opposite where I live. In fact, in my region of the country, folks would be more likely to paint targets on the homes of liberals and other pro-tyranny types.
Bottom line - I think you're buying into an apocalyptic vision that will never come to pass. At least not in this country. Americans are simply not going to roll over and succumb to government confiscation of arms like you think they will. Not by a long shot.
I never though the church would roll over and accept gay marriage either, or how about men in ladies bathrooms, or muslim prayer rooms in public schools, or Gays in the military.
I have been waiting 50 years for these staunch supporters of the Constitution to actually support the Constitution. Wake up half the voters voted for socialism and if Hillary had not stole the primary we might well have elected a communist President.
