My idea why:
They don’t care about the guns. They want the people.
They want the people to be arrested and put away. They want us not disarmed, they want us dead.
So by “taking the guns away” we disappear into the fray - and we start to look like other tools and zombies that support them. They need to separate us.
Almost sounds like one of those Alinsky principles Obola and the Beast love so much.
