I think that the concept of argument does not apply.
Confessing criminal behavior by warning other people in advance that you will take their guns is a weak position, giving up the power of autonomy - if you can understand the point.
The power of self-government, self-defense, is accumulative as each individual refuses to budge an inch in the wrong direction.
If you think you can change a person's mind by persuasion, as if apply the old saying "You can catch more bee's with honey, than with vinegar." then I think you have given up too much ground in this fight.
Liberty is up against people who create arguments so as to have the victims fighting each other, growing weaker, wasting their power (time and energy) fighting, and then they swoop in to control the weaker victims.
The battle, if it reaches a stage where guns are being taken from the targeted victims, is no longer an argument over the right and wrong of human behavior, the criminals are no different than a natural disaster, a rabid dog, a deadly virus, a perfect storm, and either the victims are going to suffer greatly because they are too weak, too powerless, too vulnerable, or the powerful (as in armed with autonomous defensive power) targeted victims are going to do the right thing and avoid those injuries somehow, each in their own individual way, including many as yet not known tactics, methods, that can side-step, avoid, and completely disconnect from the criminals and their crimes.
To be funneled down into this "debate" over the current affairs of the criminals, and their minions, and their targets, and their supporters, is to be sucked into the vortex, being a part of it, participating in it, lending it moral and material support, instead of preserving that necessary power needed for mutual defense against it.
Of what concern is it to any honest, productive, kind, good, person that some of our number has been slaughtered by a few very evil people and done cleverly, as these perpetual crimes are done with the help of the victims, as the victims are led to believe in falsehood without question?
If it is a concern, then why regurgitate any of the lies, any one lie, why add that support to the enemies of honest, good, productive, free people?
Call the criminals for what they are, hold them to account for what they do, and for the lies they claim to be true, and in my opinion: refuse to engage at all, including these supposed arguments, or debates, where the deck is stacked in favor of lies.
It is not "government" slaughtering people. Specific people are signing the orders, specific people are following the orders, specific people are lending moral support, and specific people are carrying out those orders, and those specific people have names, and those specific people wear clothes, and those specific people, each one, can stop being criminals and stop hiding their crimes behind the false front that they call government.
If you call their crimes government, who benefits?
If anyone injures an innocent person, disarming them, in any way, then a crime is committed upon that innocent person, and who should care about it, and who should do something RIGHT about it?
Who is next?
