There are many social issues that humans are trying to deal with, and racism is only one. Why are you focused on racism rather than education reform, tax law, access to the courts, separation of church and state, illegal immigration, or any other major problem? All of these issues seem more interesting and important to me than anti-racist work. Another reason is that anti-racist work is often thought to be strongly tied up with, and is often used to signal, particular ideologies and political and economic opinions.

Getting back to the point, I understand you're using racism as an analogy for the way humans see paperclippers. What I'm trying to explain is that some types of discrimination are justified in a way that racism isn't. For instance, I and most humans have no problem with discrimination based on species. This is a reasonable form of discrimination because there are many salient differences between species' abilities, unlike with race (or nationality). Likewise, paperclippers have very different values than humans, and if humans determine that these values are incompatible with ours, it makes sense to discriminate against entities which have them. (I understand you believe our values are compatible and a compromise can be achieved, which I'm still not sure about.)
