Political subtlety or missing the real solution?

When is conservative subtlety just not enough? Talking about "growing political and regional disunity" in the U.S. (Chronicles ) without mentioning the core of social disunity coming from ethnic and racial disunity seems like talking about religion without mentioning the soul or spirit.

Does there come a time when the biological origin of much of our social behavior has to be mentioned if we are to successfully solve our social problems? Ethnic and racial competition and disharmony are not evil they are natural elements of real human nature.

Subtlety is one important conservative element in politics and in art, missing the real solution is another. We eventually will need ethnostates as "contiguous regional republics," which happens anyway after the fall of empires.

Even so, I see the importance of using subtlety regarding such a volatile subject, especially in a society so heavily brainwashed with the political correctness of cultural Marxism.  But someone has to be politically incorrect on this subject.
