I heard all that wacked out leftist drivel in the 60s. At least get a new song, yours is worn out.
Do a little research on “Militia”. It is most definitely mentioned in the Constitution.
It was a sociatal norm at the time, and the founders felt no more compelled to spell it out than define water as being wet.
If there's anything worn out, it's your ability to reason critically. Or to even present a cogent argument.
But since you've missed the point entirely, there's probably not much sense in continuing this "discussion." Read a book sometime. Expand your mind. Before it atrophies completely.
