What is your personal breaking point for armed resistance?

The more our rights are infringed upon, the more people keep talking about how an armed revolution is coming. I'm asking here because I want to know what everyone's breaking point is.

My breaking point is a national registry. As soon as someone comes knocking at my door asking me for the serial numbers for every gun I own, I'll go into straight up resistance mode.

My dad said that the only thing that will shy Congress away from trying to abolish the second amendment would be a million armed Americans marching to DC to peacefully, but forcefully make them back the fuck off.

Edit: I swear to God I'm not the government...
