It depends on what you mean by whites warring whites. If you mean whites warring whites that are subservient and subordinate to non-whites (especially a particular conniving subgroup) I would have to disagree. You have to take your own side to play the game and you have to be willing to play the game. Anyone who disrupts that should be disrupted. There are plenty of whites that would shoot their teammate before shooting the enemy team. Our enemies don't win by direct warfare with us, they win by turning us against ourselves. Paradoxically that means you have to eliminate your own. Notice your enemies constantly infight and purity test and enforce ideological conformity.

"If I had but one bullet and were faced by both an enemy and a traitor, I would let the traitor have it." -Corneliu Zelea Codreanu
