Whether it had the authority or not is irrelevant.
It is completely relevant! You can't just discard the Constitution!
It did change the meaning of the Constitution when it made most of the rights applicable to the states
They always were. The most of the Bill of Rights was always applicable to the States as well The 1st and 10th amendments are not.
and we have been abiding by that changed law for many years. You can argue it had no authority to make those changes, but it did and that is current law.
It is NOT current law. The 1st amendment still only applies to the federal government. The Constitution is the ONLY authoritative law here.
Maybe Congress did not have the authority to create Social Security,
It didn't.
but they did so and we have been operating under that law since the 1930's.
But it is unconstitutional. It is also collapsing. It is socialism.
Arguing whether Congress had the authority is irrelevant to today's governmental system.
Then you are saying that we are no longer a republic. You are saying the United States is an oligarchy, and that there is no Constitution.
You only believe that if you don't like the policy.
Nope. The Constitution as written is a package deal. It is YOU that applying it selectively. Inversion fallacy.
If we go by what is written Congress only has the authority to regulate naturalization but not immigration.
Immigration is part of naturalization.
However, you give a more liberal interpretation to that term giving Congress more power than the Constitution gave it.
It has always meant that, even before the Constitution itself was written.
Definitions of naturalization do not include immigration (see Blacks Law Dictionary)
False authority fallacy. Black's Law Dictionary is not the Constitution, nor the Magna Carta, nor any other founding document of any nation. It is a useful reference, but it is not authoritative in any way.
and naturalization laws included nothing about immigration.
Naturalization IS part of immigration. It always has been, even before the United States itself existed.
You claim immigration was part of naturalization
That's right.
--but not according to the plain, literal words of the Constitution you pretend to follow.
You are changing what 'naturalization' means. Redefinition fallacy (immigration -> void, void -> naturalization). There is no one to naturalize without immigration, dude.
The same thing applies to laws giving the president emergency powers and many other laws or presidential actions.
Congress created a general budget item that the President can spend on anything by using an 'emergency powers' declaration. That is a budget item. Completely constitutional.
They only did that as a deal with those who opposed the new Constitution as a condition for their ratification of the document. If they thought the Bill of Rights was necessary they would have included them in the original document.
The Bill of Rights changed NOTHING in the Constitution itself. Everything stated in the 1st ten amendments already existed in the Constitution. These amendments only serve to clarify certain points.
They said government had no power to limit speech, press, etc.
That's right. It still didn't BEFORE the 1st amendment was added.
therefore it was not necessary to have a provision saying they had no power to do so.
Correct. It is not necessary. It is a clarification of what's already there, that's all.
Amendments 2 thru 9 did not change anything in the federal government either. Their effect was to extend certain restrictions to the States as well. Amendment 1 and 10 do not apply to the States (except for a portion of amendment 10).
