I believe militia implies you are not employed by the government.They are by definition Civilian.No military connection required.It does NOT say "well regulated Army"
Another important thought,the "well regulated militia being necessary for the security of the free state" is a rationale.It is not the statement,it is not the point.
"The right of the PEOPLE (not militia,not under 45,people! Includes women!)
"The right of the People to Keep and Bear Arms(not vague at all.Have them at home,pick them up,hold them)....Now,check this out,seems quite powerfully clear: "Shall Not Be Infringed".
So,what is the problem?It says what it says.
