In the words of Muhammad Ali, Jr.,
"It's not just black lives matter, white lives matter, Chinese lives matter, all lives matter. Everybody's life matters. God loves everyone."

The Bill of Rights is like a family portrait, and the Second Amendment must not be excluded from the picture.

On the basis of both text and history, the 2nd Amendment guarantees an individual right to keep and bear arms. It is a civil right, and a citizen's right is not dependent on his zip code.
From the Supreme Court in NYSRPA v. Bruen (2022):
"... [T]he Second and Fourteenth Amendments protect an individual’s right to carry a handgun for self-defense outside the home. ... When the Second Amendment’s plain text covers an individual’s conduct, the Constitution presumptively protects that conduct."
Amicus brief supporting NYSRPA, by Cottrol, Dowlut, & Beard

The Supreme Court cannot throw out Heller without throwing out Obergefell. The Court ruled as fundamental both the right of an individual to own & possess arms and the right of an individual to marry a person of the same sex. However, Heller’s holding is based on a longer history and a stronger foundation than Obergefell's holding.
I.e., if Obergefell stays at the party, so does Heller. It is a marriage pronounced by the Supreme Court.

If the rule of law is to prevail, Supreme Court decisions that hold that a right is fundamental require obedience by lower courts.
In the wake of the Supreme Court’s Heller and McDonald decisions that clarify and protect Second Amendment rights, federal and state inferior courts engaged in massive resistance.
