No, it shouldn't except in a very broad sense and within a much larger context.
There are entire branches of Judaism that see certain social behaviors as primary and understand Jewish law to focus more on those causes than on others. If they were in charge, maybe they would use that understanding to drive domestic policy.
No. But did you by taking a verse and deciding that your understanding of it applies here?
Because to her personal understanding, that is an appropriate thing to mention. Is she more Jewish than I? Is her understanding more normative than that of many others? Why is it persuasive to you while what I say seems not to be?
That's a much more complex question. First it assumes a monolithic construct called "Jewish culture" then it invokes the idea of "hospitable" which is up for discussion. And of course, then it calls into play the constant tension between religious law and secular law.
The verse should be applicable to everyone and I find it applicable here, now you may think that it should be applicable elsewhere or should not even be used to make a point. The main point is right and wrong action. Whether you want to admit it or not there is something wrong with the Israeli government. Palestinian and Israeli issues aside, this is but a microcosm of the social issues I believe Israel is facing. You said (and I'll bold it) in the following:
"
Why is it persuasive to you while what I say seems not to be?"
Because it's not the first time I've seen that. Before I make an opinion especially something like this I do my own research on it. Now, I'm not saying her views are normative of the society as a whole because I'm sure it isn't, but I'm more concerned about what is more influential. For example the reason why the United States backs Israel politically is because of some utilitarian ideal, but because the religious right wing conservatives who have money have influence and power. They don't care whether Jews believe in Jesus or not, they're looking for spiritual currency and influence in that region. The Israeli army could kill 10 million kids, men, and women and the right wing conservatives will not bat an eye.
My main concern is about right and wrong and to me this is wrong. Of course I'm an "outsider" this is why I believe the U.S. should rescind any ties to any Middle Eastern politics but that is another thread to discuss on that matter.
With respect to Jewish culture I'm not trying to make an assumption of whether it is a monolith or not, but I'm merely looking at it from simply the custom of the people in that region. From my understanding of fellow travelled classmates, the people in that region are very hospitable, or perhaps they're referring to the Palestinians. Then again I don't know but I'd like to infer that Jewish hospitality of a foreigner, ought to be like what God mentioned in the aforementioned verse.
