LoveUni,
If you, as a white person, had a ten year long narrative of thinking that every black person around you was screwing you over for being white (but also thought that gay white men were also screwing you over because you're straight), and then after a black guy blew up a white civil rights church and said he was out to get all white people and the race war had started - you killed two of the people you thought were purposely were trying to get you, I would say you were paranoid delusional with the main focus being perceived attacks on your race and sexuality.
That's because the psychological trigger in your case is imagined external persecution as opposed to your perceived superiority based on race. Swapping the races makes no difference in that case, the conclusion would still be the same.
