This is probably what people were reading in Germany in 1939, thinking, 'they must be kidding, they must be kidding'.
But they weren't kidding, they were serious, it's called a precursor. Any firearm legislation would have been outright illegal in 1900. 100 years later there is a new law proposed every week.
This stuff is real, these people and the interests they serve are real, the plan is broadcast in the open. In his very article he specifies no-one ever should ever know what recoil from a firearm feels like. That is the goal. It's real, they aren't kidding.
And the people who are anti-gun might not be pro-police state, but once the guns are gone they're going to get a police state along with the rest of us anyway.
