"June 4th" was a young Chinese student and democracy activist who was part of the Tiananmen Square protest. That protest was crushed by the People's Liberation Army under the direction of the Chinese Communist Party. On Saturday, "June 4th", who is now a naturalized US citizen and a firearms owner, participated in the rally for gun rights on Saturday at the Massachusetts State Capitol.
"June 4th" refers to the day that the People's Liberation Army fired upon the students and activists in Tiananmen Square killing many hundreds of them.

The part of "June 4th"'s speech that really stuck with me was this:
Do you know that the Chinese Constitution guarantees almost all the nice things we have here? It is written that Chinese citizens enjoy freedom of speech and religion, they have human and property rights, and that such rights cannot be taken away without due process of the law. And do you know what? Chinese people do not have the right to keep and bear arms. I assure you all those nice guarantees, are not worth the paper they are printed on, because when the government has all the guns, they have all the rights. <Think about it.
I was not born a citizen of the United States, I was naturalized in 2007. In 2008, I became a proud gun owner. To me, a rifle is not for sporting or hunting, it is an instrument of freedom. It guarantees that I cannot be coerced, that I have free will, and that I am a free man.
Now suppose the 20 million Beijing citizens had had a few million rifles, how many rounds should they have been ALLOWED to load into their magazines? 10? 7? How about 3?
