What other right can simply be denied to adults? Do you have to get permission from the government to exercise free speech? Can you be denied your right to remain silent based on what state you live in?

Treating the 2nd Amendment like a first-class right is hardly ‘expanding’ it.

What other right can simply be denied to adults?

The right to life and liberty, by any gun owner, at any moment, for any reason.

What the hell are you talking about? Murder is illegal.

Murder is illegal, but the supreme court has said that it's okay to sell murder weapons to people who are obviously going to commit murder.

Because the right-wing nutjobs hate background checks, and red flag laws and anything else that slows down the constant murder.

it’s okay to sell murder weapons to people who are obviously going to commit murder

Planning to murder someone is not only illegal but also a felony, which bars gun ownership. If we have evidence someone is going to commit murder, arrest, charge, and convict them.

That’s very specific… what 1st degree? What about 2nd degree murder (heat of the moment kills)?

Should we keep people from buying cars, hammers, and kitchen knives?

Should we allow overweight, insecure men with a long history of red flags to buy hand grenades, land mines and machine guns?

Some people with NRA induced brain damage will of course say yes but the reality is that we’ve already decided that there are weapon that are too dangerous to indiscriminately hand out.

And what do you know? We’re able to keep them out of the hands of domestic terrorists just fine.

Ethically? If they haven’t be convicted in a court of law, yes, we should. Otherwise you’re denying them due process. Also, red flag laws make getting help effectively illegal.
