Were you and the new owners equal under the law?
Of course you are.
The question isn't about you, it's about the civil States and the federal 'State' that they created.
They are not equal under the law.
Why?
Because the States get their power directly from the people, and the People hold the highest from of sovereignty. This makes the State inherently SUPERIOR to anything it could create, just like the People are superior to anything THEY create....like a State.

The U.S. holds Guantanamo Bay. Shortly after taking power Castro began demanding the U.S. leave Gitmo. It's been his position for 40-odd years. Considering that Gitmo lies within Cuba, a sovereign nation, then would Castro be in within his rights to shell Gitmo into surrender. And wouldn't you support him if he did, since his actions would be justified in your eyes?
If one abides by the letter and the laws of the Constitution, the US should not have been there in the first place, because the States never created the Amendment to give the federal government global powers. It only possess national ones.
Even if applicable under 'common defense and general welfare', once asked to leave by the acknowledged ruler of a sovereign country, and no treaty or other legal obligation to prove their right to be there in perpetuity, yes, they should leave.
Castro has the right to force them out if they do not.
No, the Constitution is superior.
