Answer:
The September 11 attack seriously damaged democracy.
Step-by-step explanation:
The September 11 attack strongly damaged democracy, especially in relation to the freedom that democracy proposes. That's because these attacks generated a strong wave of government distrust. As we can see in the article, governments, as a way to protect themselves from possible terrorist threats, initiated a system of surveillance on citizens, which violated the limits of freedom. This extreme surveillance prevented the free exercise of religion, harmed immigrants and their descendants, in addition to promoting accusations and persecution of innocent people. This undermined people's trust in governments, causing them not to feel represented by those they put in power, that is, they lost faith in democracy.
