A lot of people in this world have grown up in bubble-like environments where discriminatory ideas and ways of living are passed on from generation to generation. A lot of times this happens without questioning anything, and marking people for life.
For the people in question, there is no incentive to 'learn' why they shouldn't discriminate, or to ask themselves if they are wrong acting this way.
Is it possible to mitigate this through technology? Can incentives be created via technology so that this is appealing to new generations? Can you come up with a way to do so?
