In a post-9/11 world, has America progressed in its inclusiveness? Why or why not?

"Inclusiveness" is a very broad term. In many ways, American society has become more inclusive since the early 2000s. For example, bans on same-sex marriage have been overturned by the Supreme Court, Americans have become increasingly aware of issues affecting transgender men and women, and the decades since 9/11 witnessed the election of Barack Obama, an African American man, as president. These developments would have been unthinkable during the all-too-recent past. At the same time, there are important ways in which society has become less inclusive, particularly in the last few years. White nationalism and racist groups are on the rise, both in terms of membership and visibility. We are still only beginning to learn of the size and scope of the problems facing women in many workplaces, including harassment, assault, and discrimination. Courts have overturned protections of voting rights for African Americans and other minorities, leading to laws (voter ID legislation, for example) that many Americans argue are discriminatory in intent and effect. The systemic effects of racism are still in evidence everywhere in American society, including employment, housing, education, and law enforcement. The threat of terrorism often emphasized by invoking 9/11 has been used to argue for laws restricting immigration from predominately Muslim countries and to stoke xenophobia in general. Immigration remains a major debate in American society, with hardline positions moving from the fringes to the mainstream. By these standards, it is difficult to argue that the post-9/11 United States has witnessed the expansion of inclusiveness. The United States has long been characterized by differing notions of who belongs in society, and these debates and struggles persist, perhaps even in greater intensity, after 9/11.
