Racism is wrong and right, in different ways. Racism is stupid that we say all humans are the same, even though, as mentioned, all races have different traits, cultures, beliefs etc.
However, the real deal with people against racism is when we say that the races are unequal to each other. For example, americans in 1963 gave african americans no rights, thus being racist. These days, racism doesn't really exist imo.. I mean yeah, the woman was denied because of her race, but thats kind of fair, isn't it?? It's just like somebody with any quality or trait that isn't wanted in this specific area applying and getting denied, there's no need to take offence to it, it's just the way business works.
