Except, you are not responsible either for the sins of your ancestors, or their greatness. You are responsible for what falls within your own personal sphere of control -- what lies "within your power," as the Stoics liked to say.

I know that full well. I alone am responsible for what I do. I am not responsible for what anyone else does.

Personally, I don't believe it is wise to concede any point to the left that is invalid or untrue. A just man does not use unjust arguments. White men should not adopt the habits of either niggers or Jews.

I agree with you. I don't see it as conceding the point, but disproving it. The idea is to use the example they give against them. If X is true, so must Y be true. Simple logic.

It is not conceding anything. It is proving that their argument is just plain dumb.
