2A tied to racism, white supremacy: Letter

What kind of funky shit has he been smoking?

So the author thinks the Founders had to put it in the Bill of Rights that the Militia (an army of citizens available to be mobilized for military service) had "the right to keep and bear arms".
Perhaps he will be good enough to tell me where the Constitution states that the army Congress is authorized to raise may be manned by armed troops. I have found no such statement.
Of course, there is no need for such an explicit statement that "the army (or militia) may keep and bear arms" -- it is implicit that a militia or an army is an "armed force". All such "armed forces", be they militia or regular army, manned by enlistees, draftees, volunteers, or mercenaries, are manned by armed troops.
If that fact does not tell the author that the 2nd Amendment is not the protection of the "right of the Militia" to be armed, then perhaps he should re-read the 2nd Amendment. It states "The right of the people [and not the "Militia"] to keep and bear Arms shall not be infringed".

Huh?
