First of all, the Jews who lived in Israel before it became a state in 1948 were "Palestinians" and second of all, people just say "Jews" when referring to the Hebrew nation with the shortest term. What makes you think "Palis" is derrogatory? And isn't that the least of their concerns if they are urinating in a house of worship?
"Jew" is an accepted term found in any dictionary. "Hebes" and "Palis" are contractions, that I strongly suspect both groups, to which they refer, would find derogatory. Is it possible you are being genuine in your protestations? I confess that my suspicions were that your position was probably more akin to that espoused by the particle from Texas in post #55 (who so eloquently corrected our spelling).
What is not clear from the article is whether any proper sewage disposal was left in place during the siege. I noticed that "Two Palestinian men were killed by gunfire in the church compound last month and another was later wounded". I wonder if any of them were perhaps attempting to relieve himself outside. I also wonder what any structure would look like, after dozens of people were confined there, for more than a month with amenities cut-off perceiving an imminent armed assault?
