In my opinion anyone in positions of authority or power over general citizenry (politicians, judges, etc) and all emergency service jobs that are charged with protecting our lives (medical services, police, fire, etc). As far as other private businesses they can hire whomever they like as long as the business or the individual is not discriminating against their communities. For instance, I dont really care if a Ku Klux Klan member is a cook at Applebee's (just using this as an example) as long as he/she is serving general public equitably and fairly, and not refusing service or purposely giving poor service to people of different ethnicities or religions. Outside of emergency services or postions of authority I dont really care as long as they are doing their jobs.
Are you the 1%? How do you determine who is biased? Is it whomever doesnt agree with you or share your worldview? I admit that I am biased. I am biased toward sociological, psychological, and other cognitive fallacy studies and experiments that prove subconcious racial and ethnic biases are extremely prevalent throughout our society. I also biased toward analytical data and empirical evidence that consistently show that race does impact outcomes. You seem to be more biased toward random YouTube vidoes of people who fundamentally misunderstand that research and post their incoherent thoughts on the internet. So... yeah. We all have our biases.
In the field of law enforcement absolutely. I would expect the same if someone was a member of a black separatist group or an anti-Muslim group or any other hate group. This job isnt the same as being a line cook at Applebee's. This is a job that literally determines who has their lives ruined by going to jail or prison, and in too many cases who lives and dies. So the answer is yes
It must be easy to maintain foolish stereotypes when you can just dismiss all data and studies into a matter because it conflicts with your personal and small window of the world you live in on a day to day basis. http://insight.kellogg.northwestern.edu/article/does_immigration_increase_crime http://www.researchgate.net/publication/256081616_Undocumented_Immigrants_as_Perceived_Criminal_Threat_A_Test_of_the_Minority_Threat_Perspective http://www.tandfonline.com/doi/abs/10.1080/07418825.2012.659200?journalCode=rjqy20#/doi/abs/10.1080/07418825.2012.659200?journalCode=rjqy20
