No, I haven't seen any evidence indicating that caucasians are predisposed to narcissistic personality disorder.
As a white person, NPD seems to effect older white men (50's and 60"s) more than anyone else. I worked in an industry where I had to speak to a lot of different people on the phone and old white men were the biggest pains the a%% to deal with. Nothing is more annoying than hearing about how much "better" everything used to be from an old white man.
Especially when you know for a fact his whole family hates his guts and can't wait for him to kick the bucket. And yes I'm bitter because my Dad is definitely a narcissistic chronic liar.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
