The guy doesn't even know what "regulated" means. In the context of the second amendment, it is obvious, as it pertains to "a well-regulated militia":
2: to bring order, method, or uniformity to <regulate one's habits>
How would it make sense for a militia, independent of the federal, and/or state government, to conform to this definition:
1 a: to govern or direct according to rule b (1): to bring under the control of law or constituted authority (2): to make regulations for or concernin
Those are just from Merriam Webster.
The Oxford English dictionary provides more evidence that shits on that Brady cocksuckers argument of the word.

The meaning of the phrase "well-regulated" in the 2nd amendment
From: Brian T. Halonen
The following are taken from the Oxford English Dictionary, and bracket in time the writing of the 2nd amendment:
1709: "If a liberal Education has formed in us well-regulated Appetites and worthy Inclinations."
1714: "The practice of all well-regulated courts of justice in the world."
1812: "The equation of time ... is the adjustment of the difference of time as shown by a well-regulated clock and a true sun dial."
1848: "A remissness for which I am sure every well-regulated person will blame the Mayor."
1862: "It appeared to her well-regulated mind, like a clandestine proceeding."
1894: "The newspaper, a never wanting adjunct to every well-regulated American embryo city."
The phrase "well-regulated" was in common use long before 1789, and remained so for a century thereafter. It referred to the property of something being in proper working order. Something that was well-regulated was calibrated correctly, functioning as expected. Establishing government oversight of the people's arms was not only not the intent in using the phrase in the 2nd amendment, it was precisely to render the government powerless to do so that the founders wrote it.
