It's a Bill of Rights. Apparently, your definition of a Right is different than mine. You go ahead and give up your Rights when the Dems finally repeal the 2A....
A right is whatever the government decides to give to its citizenry subject to the citizenry deciding they want a different government.
You have no natural rights. Perhaps it is because I am not religious, but I am not seeing anything god given. You have no natural right to life. If you did, such a thing as a stillborn baby could not exist. You have no natural right to pursue happiness. All of this stuff is stuff our founders decided was really important though and built it in to the constitution. Shortly after they went "oh, you know what, we need to enumerate some other restrictions on government" and came up with 10 amendments to the constitution. Actually it was 12, but the first and second amendments were not adopted by the states, just 3-12 in the circulated list.
James Madison believed they were important to preserve liberty of the citizens. But they are not rights granted to citizens, they are expressly restrictions upon the government.
If the 10 in the bill of rights is so darned important that they should never be amended then I guess we need to amend the constitution saying those 10 are sacrosanct and now no amendments or do overs for those 10.
The framers intentionally made it hard to amend the constitution, but they also recognized they might have missed something or that society changes with time.
If they hadn't, black people wouldn't have citizenship among other things. Presidents could continue running for office election after election (lets not forget FDR won 4 times in a row before the constitution was amended).
