Read the opinion in DC vs. Heller. Almost the entire ruling, on both sides, focuses on the words and meanings. For example, you highlighted the operative clause in the statement, but you cannot simply ignore the prefatory clause.
One of the key points is defining what 'militia' is. One school of thought constitutes a militia as anyone able bodied to fight in military service. Another interprets militia as someone actually engaged in an organized state militia. The Constitution doesn't define a militia, and both meanings of the word were common at the time. Strict constitutionalists tend to fall back on what words meant at the time they were written, so this doesn't help matters. It's definitely not black and white.
Even in upholding the right to bear arms in Heller, the court specifically upheld the fact that restrictions CAN be placed on gun ownership.
"Although we do not undertake an exhaustive historical analysis today of the full scope of the Second Amendment, nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms."
There are also reasonable arguments to be made (outside of Hello, in non SCOTUS decisions) that weapons for self defense are reasonable, but private citizens don't need assault weapons, and shouldn't be allowed to possess them. I tend to agree with this idea, but that's just my personal stance.
In today's civilization, citizens don't need assault weapons. But the 2nd amendment wasn't written to defend citizens from this environment; it was written to defend them from more hostile ones.
There could very well be a time in the future where an assault weapon could be exactly what a family needs to keep themselves safe.
Pros and cons to both sides, and as you said, not so cut and dry. But I lean more towards allowing that kind of gun ownership.
