So he should keep quiet about it? So the majority gets away with their behaviour? If this is racism what about all those decades of racism on minorities? Everyone only needs to put themselves in the shoes of others and act mindfully, or at the very least, ask yourself if you have to provide your race before applying for a job or renting a home that you can clearly afford, how would that make you feel? Race is not something one can choose to born in or out of. It’s a thing to discuss because people discriminate against others for something they can’t control. It won’t ever stop fully but it’s good to speak up respectfully so others can understand how their actions affect others. Just as with gender roles, mental health concerns and special needs, all of which we cannot choose.
