Nope. Study US civics. The Constitution can be amended, which is unlikely — and also interpreted by the Supreme Court, which is what one of its key purposes is.

Too bad it sounds like once again you are on the wrong side of a history you disturbingly misunderstand.
When anyone uses the “wrong side of history” shibboleth, it means they know their argument is weak.
If you are betting on a change of the interpretation of the “militia” clause to bring about your wet dream of a gun-free America, you’ll be waiting until you’re in the grave.
But that’s fine — it will give you something to do and keep you out of other mischief.
