Diversity has advanced quickly through many Western institutions creating dysfunctional bodies. This is the focus of an excellent article  on the disastrous consequences of implementing diversity in a security sensitive environment entitled Diversity: An Ideology.
The ideology of diversity is simply social Darwinism - the term being a mindless transplant from the ‘biological diversity’ of life on our planet – as if humans were no different from other living creatures. Diversity: An Ideology gives an account of the security failure within the US army with regard to the terrorist psychiatrist Major Nidal Mali Hassan of the Fort Hood massacre. This very well documented narrative shows how diversity has conquered crucial US security institutions.
After Bill Clinton’s introduction in 1994 of the Gender Integration of Basic Training program to encourage female recruits, gender “discrimination" was implemented and complaints ensued. An independent commission was set up to investigate the cases. It concluded strict separation of genders in housing and basic training just as the Marines had been doing all along. However these recommendations were rejected. As a result quotas along the lines of diversity were even increased in face increased.
The English professor Bruce Fleming of the US Naval Academy found that
21 percent of the 2001 and 2002 classes were admitted on a “minority" basis, had SAT scores 200 to 300 points below the Academy’s average, and were evaluated “on a separate track" from non-minority students.
The joint policy of encouraging diversity and the ban on racial profiling have pretty much pervaded and nearly corrupted the American security system. For instance, in April 13 2004 the Attorney General testified before the 9/11 Commission that, “the single greatest structural cause of September 11th was the wall“ in the Justice Department that separated intelligence cases from criminal cases in order to prevent race, gender, and ethnicity from being used in national-security investigations".
