Let me give an in depth example of how maybe a detective would effectively use discrimination in an investigation, therefore proving that discrimination is a viable and tolerable tool in certain professions. Keep in mind that all situations I propose are completely hypothetical and should not be compared to real life events that have occurred to keep the neutrality on the subject.
A German government building was bombed by Hindu extremists. Fearing another attack, detectives get to work on securing the countries important facilities and following up on suspected attacks. Camera footage shows a man with typical Hindu religious clothing entering a courthouse and blowing himself up. The country sets up a comprehensive surveillance network over the internet and cellular networks. They highlight suspected terrorists based on certain keywords; Praise Kartikeyah, bomb, bombs, ied, explosive, etc... They then follow up and put those suspected terrorists on a watche list looking for incriminating evidence that would lead them to being detained and questioned. All this prevents most preventable terrorist attacks from a specific and obvious threat utilizing technology, and discrimination, or in this case good police work.
Well it is probably unlikely that there will be a day in the near future that we all get along despite diversity and difference, we're humans. The human race has adapted to different regions and environments that have molded and shaped their entire life. Culture, diet, skin color, body chemistry, physical features, and much more.
Prejudice still exists based on appearance, and the brain is naturally wired to discriminate for attractive faces. Religions conflict each other and has been the sole cause of most wars in human history. You cannot end discrimination because conflicting ideals still exists, and certain ideals cannot adopt the tolerance towards differences. So the only way you will ever get rid of discrimination is using discrimination to exclude those ideals out of society. Ironic? Very.
I also want to point out that there was never a time in human history where we did not discriminate each other, so there is nothing to separate us from. There wasn't some universal social tolerance standard at any point of the existence of life itself. So any progress we've made has only been getting better, but that is subjective.
It really all depends on how that discrimination is used. For example, police officers utilize it in areas where it is statistically likely for a crime to occur. We would be wasting tax payers dollars if we didn't put police officers in places where crime was likely to happen. Employers also discriminate employees based on their criminal record, and that is fair.
Of course using it in a way that that violates certain rights "unreasonably", that shouldn't be allowed.
