there were 100,000 who flew ethnic cleansing they started and than failed to complete. Some flew because they feared for own life, after committing atrocities, others flew because they felt that living in Jewish neighborhood is a humiliation to an Arab ( you do not know of Arab racists, do you ) The 100,000 who flew, are welcome to return, and we not only do not expected any trouble, we want them to return. Whatever they do is their choice. But than, these 100,000 have nothing to do with daily shootings. They flew it... but I don't think you will get what I say without a good doctor of mind. The bottom line, Arabs lost war on Israel, long time ago. Your revanchist agenda and protracted murder of Jewish nation on ethnic grounds by Arabs is as asocial in its rooting as any other troubled mind.
