There are passages that are endearing in those works, but that passage you quote is not one for me. That's frankly kind of shoddy. It's circular, repetative, stilted, and there's not any point to it.
I happen to like Hemingway and I happen to like The Sun Also Rises, but I am taken aback by the anti-semitism too. I only excuse it for it's time and place. But there's nothing notably redemptive about the jewish slurs that occur in the novel. It's definitely not Hemingway's finest moment to say the least.In defence of this: it is very easy to notice the faults in someone we do not happen to like - not that being Jewish is a fault. I do not think the characters (and by extention, Hemingway) are naturally anti-semitic, but the very fact that he is Jewish, and the negative notions they derive from that fact, arise from their dislike of him. In dealing with Jacob Barnes, for example, if the characters happen to dislike him (and we were privy to their thoughts), Jacob's impotence might be a point of contention and ridicule.
