The 9/11 attack was a turning point in the American society, but also in the Muslim world. Because of this attack, global offensive started against the Muslim extremists, and also a big anti Muslim sentiment has developed among the people in the United States, mainly of fear and disgust from the 9/11 attack, as well as other attacks performed by suicide bombers. Because of this, in the United States, a Muslim person is seen with skepticism and as not trustworthy, and it also contributed to the segregation of the Muslims, as well as people keeping away from them.
For a start, the surveillance in airports throughout the world has been modified ( full body scans, long lines, no liquids allowed, etc). Society became aware of terrorism and deportation since 9/11 was massive. Before that date, society has never heard of Al Qaeda, Bin Laden, Taliban movements and terrorist groups.
This caste system put people at a higher form than others, with the highest on the caste system being able to come back as another high form or ascend. Brainliest please.
