The Chinese government slaughtered thousands of their own citizens in Tiananmen Square for speaking out against government oppression.
And the people had no way to defend themselves.
Because the government had already taken their guns.
Once all guns are registered and they know where they are, the next step is always to declare some kind of phony emergency requiring that all guns be outlawed and confiscated.
It has happened throughout industrial era world history and the party now in power intends to do it here, believe that.
