Extinction of species, sure. Others have done so, too, though. But yes, we've done a lot of a-bit-too-successful hunting... That's a real shame.
But as for the other two, the Manhattan Project, wasn't it largely formed by jews? Certainly headed by one. Not white.
As for the alleged Holocaustâ„¢... It never happened the way you think it did.
I'm sure it didn't, if only because my own thoughts and imagination from the safety and comfort of my own life cannot adequately encompass the horror and suffering of that time. Neither the historical record, nor the accounts of Holocaust survivors (including some I have personally known), however, support any form of revisionist denial.
As for Jews and the Manhattan project, first most Jews I know are quite white. Second, if you look at the roster of participating scientists, most were not Jewish. Third, the project was directed, promoted, and eventually implemented by politicians and military leaders, most of whom were not Jewish. Just one more thing that cannot be blamed on Jews. (Is the desire to blame others for one's own actions typical of these "superior whites", or just of you?)
I understand that your identity as seen from the outside is inescapable - and furthermore, how you are seen effects how you see yourself. This has been called "double-consciousness" and I think it's a concept that everyone who is interested in this topic should be familiar with because it's just that powerful.
That said, a lot of the answers here seem to be addressing whether or not the identity is something that affects you. I think you'd have to say yes, unless you're oblivious to the world around you.
We are obviously affected by how other people see us, because the behavior of others is affected by their view of us. The fact that that view is often incorrect, based on mistaken assumptions or even stereotypes, does not change the fact that it influences interactions. Someone who hates blacks, for instance, may act disrespectfully toward a black person, who is then on the receiving end of the disrespect, while a white person receives better treatment.
Note, though, the distinction between the reality of the person and the impression others have of them. A black person, for instance, can be lazy, uneducated, and uncultured, just like the stereotypes; or he/she can be well-educated, industrious and successful. Which they are is independent of other people's view of them in a given encounter. If the majority of interpersonal encounters, however, expose a person to a certain view of them, they can internalize that view and start to live up (or down) to it. This gets into the next question.
But the question I'd like to pose going a little deeper is do you form your identity around simply being born X Y or Z or do you create an identity of your own through it?
Everything in our makeup and environment affects our identity: gender, race/culture, physical attributes, upbringing, even where we live. This is the hand we are dealt; it is up to us how to play it. People often don't realize that they can draw additional cards, or even discard some. They mistake a 3 for a Queen, or don't understand whether Ace is high or low, or don't know what to do with a wildcard. In real terms, this translates into failing to understand and develop one's strengths and talents, remaining unaware of the variety of available choices, and accepting to be constrained by limitations that are not real. All this relates to whether one has an internal or external locus of control.
As for myself, I did not so much create my own identity as allow it to develop on its own, periodically clearing away any weeds, pests, brambles, or trash that threatened to stunt or constrain it. I was born many things, but it quickly became apparent to me which are relevant and useful in reaching my goals, and which are relatively inconsequential.
