Obviously, people will be deeply affected by what they've seen in person with their own eyes.
But there are Israelis who have witnessed terrorist attacks, or whose families have been killed in them. If personal experience alone were enough to "prove" right and wrong in a conflict like this, we would be left with a contradiction.
This is a news article I saw today which has some relevance:

You do make a point that people are affected by what they've seen. You say that there are people who have been killed by terrorist attacks in Israel. This is true too, and that is truly terrible. Let's put this in perspective though: nearly one hundred times more children were killed in Palestine than Israel in
the last four years. That means that to be fair, for every time someone says "it's terrible that that child was killed by Palestinian terrorists," that someone
should say "it's terrible that that child was killed by Israeli terrorists" around
a hundred times.
Here's a slightly more relevant article:
http://www.commondreams.org/headline/2010/10/12As you can see, it's not just a one time thing. Ricercar is definitely not alone
in witnessing these kinds of attacks.
On a side note, Arabs are semites too. Since you sound interested in the
subject of Islam's beginnings, which I find very admirable when someone is
interested in history, listen to this recent interview:
http://www.publicbroadcasting.net/kuer/news.newsmain/article/184/0/1699528/RadioWestThe one being interviewed is Fred Donner, a non-biased non-Muslim Historian
who is certainly more qualified than Jonathan Kay to speak on the matter.
If you don't have time to listen to it (which would be a shame), he basically
speaks of a community of believers, Christians, Jews, and what-have-you,
with Muhammad as their leader. The funny thing is that a caller buzzed in
and asked about the very Banu Qurayza incident that the article you posted
cites. The Historian gives a very good response to it (spoiler: he thinks it
never happened).
Of course, all of that is off topic from the Israel Palestine discussion. If we
wanted to talk about racism or intolerance with respect to these two
candidates, then the champion is Israel hands down... Talk about ethnic
cleansing. Sheesh.
Thank you for considering my words.
