Over many generations, we?ll ultimately destroy their impurity and replace them completely by white-cell superiority. We call this process Assimilation and through it we will better humanity as a whole.

And that is why multiple party systems exist and that is why you must belong to one. Otherwise you are just begging to be destroyed by black, usually virus-infected, cells.
