"It noted that the Christian Europeans around him, while professing liberal tolerance, were continuing to treat Jews such as himself as different, other or outside" ... This is probably true, on the other hand, it is also probably true that many Jews will see the Christian Europeans as 'other' too.  I have many Jewish friends, and from talking to them, I know this is true.  But that's not necessarily such a bad thing, surely?  What makes our relationships interesting is in fact the exploration of the other.  Even if it's not a matter of ethnic difference (which mostly boils down to being raised with different customs), all of us are unique.

Where this becomes a problem is when you use the differences you find in someone else as an excuse hurt and persecute them.  But that's not what I read here - there was nothing in this article - beyond a description of a historic antipathy between Jews and Muslims - that was that new. Not sure I saw the point.
