We seems to have been alienated from our inalienable rights.
Now I suspect the teacher is pretty pleased about it, whereas I am depressed and angry. But the point is: the teacher has a point.
From the wikipedia article:
District of Columbia v. Heller, 554 U.S. 570 (2008), was a landmark case in which the Supreme Court of the United States held that the Second Amendment to the United States Constitution protects an individual's right to possess a firearm for traditionally lawful purposes, such as self-defense within the home and within federal enclaves. The decision did not address the question of whether the Second Amendment extends beyond federal enclaves to the states, which was addressed later by McDonald v. Chicago (2010). It was the first Supreme Court case in United States history to decide whether the Second Amendment protects an individual right to keep and bear arms for self-defense.
Nah, most of the points quoted in the article are exactly the opposite of reality. The courts have affirmed the right is an individual one, they have incorporated the 2nd amendment against the states, they have struck down prohibitions as unconstitutional, etc.
They got it wrong in so many different ways, makes you think it was on purpose.
