Well, first I think we need to look at what racism is and it's place in our reality.
1. The world is made of atoms. However, if I only look at atoms, we will never see find table, chairs, or pairs of glasses. Those things may not exist in reality in the way I perceive them. Nevertheless, I do perceive something, and it functions like a chair, table, or pair of spectacles. By interpreting that information and acting appropriately according to my perception, memory, and testimony of others, I can exist in the world that I perceive.
2. Dictionary definitions are subjective. However, most definitions attempt to point at something - whether physical or conceptual.
3. Racism exists: both as the belief that one race is superior to another and in the Mariam Webster sense. They exist in the mind as beliefs. Beliefs exist. I have them. You have them. Everyone else has them, too.
4. Moralities are also beliefs. Like all beliefs, they need not exist outside the mind in order to exist inside the mind.
5. I consider milk tasteless. Others love it. However, tasteless and love are attributes not of the milk, but of the individual who has a belief about milk.
6. Different people have different opinions as what they consider racist - just like finding milk tasteless or pleasant. The sense of something being racist is an attribute of the individual, not the object.
7. Therefore, something cannot
be racist. It can only be
considered racist.
8. The fact something cannot
be racist (once again, in the Merriam Webster sense) and can only be
considered racist is not an excuse to intentionally offend or harm others. Humans exist in societies. Those societies require cooperation to sustain themselves. Collapse will likely result in the loss of human life and well-being, which I consider a bad thing.
@Flamestrike's belief assigns orcs the attribute racist. You don't. It's that simple.
@Flamestrike's belief has nothing to do with orcs and everything to do with
@Flamestrike's perception of reality. The attribute "racist" is an attribute of
@Flamestrike's belief, not orcs.
