Ok Rambo.
Gun confiscation will begin with door to door searches of everyone’s homes...not an attack by all out military weapons.
The front door will be your first encounter with the Marxist Democrats. At that time it will be “poop or get off the pot” time for you. You will have one chance to make the decision to become a slave or at least do what you can to take out as many vermin that you can.
And i agree with you that the front door will be the first point of contact,,to a point. That door to door business would last about a day or two before the word was out and everyone knew it was happening. At that point, nobody should have front door encounters.
That should be when you invite them in for coffee, helpfully explain that you gave em all your guns to your ex wife so she could sell them. Or maybe the local evil democrat politician who took them in exchange for that zoning variance you had to have. Act really sad about it. Wish them well. Be totally sincere when you say, “see you guys around town”.
