>Does the second amendment enumerate an individual right to keep and bear arms?

Yes

>The right is conferred to the People, not the States. Nowhere else in the constitution would the phrase the People refer to States. Could you please explain how you arrive at the conclusion that it is about states rights?

The first amendment's Freedom of Speech clause is also about the rights of the people, and it's similarly been incorporated against the states for like a hundred years.

Just like almost all of the rest of the Bill of Rights, the courts have determined that if the constitution protects individual from having a right infringed on by the federal government, it also protects indiviuals from having that right violated by they state they're in.
