You cited as examples what a fair number of the "Founding Fathers" would consider natural rights, although the changes that brought them about were the American Revolution, the Constitution and subsequent Bill of Rights, the Civil War and subsequent Constitutional Amendments, and finally the Civil Rights and Voting Rights Acts of the 1960s.
As a matter of historical fact, they are not the routine actions of democratic governments. The examples I provided are typical of the incremental accretion of power by democratic governments to the detriment of individual citizens.
I can buy a gun, and in September I can buy an assualt weapon.
Don't count your chickens before they're hatched. What your calling an "assault weapon" is a misnomer, and there are many cities and states that will still forbid them. You can't own handguns in Chicago and Washington D.C. among other places, IIRC.
Current events show that the vast majority of current conflicts around the globe are between different ethnic or religuous groups who feel they have legitimate grievances.
A significant number of the recent immigrants from Latin America have not chosen to follow prior waves of immigrants and become assimilated with the rest of society. Regardless of whether it's because of the relative proximty to their countries of origin, a significant number are not planning to stay and become citizens. Instead they are behaving like an exploited and aggrieved minority. For the sake of cheap labor that's OK with you.
I see. The right to vote for non-landowners, and later blacks, and later women, and later 18-20 year olds are not as important and zoning ordinances.
Good night.
