They got their good Semites bad Semites confused.
Quite possible: In my corner of Germany (Schwarzwald), b&b operators have had great trouble contending with "Israeli" guests who didn't know how to, e.g., separate waste streams or otherwise conform to basic standards of behavior - to the point that they have begun refusing to accept reservations from guests from Israel.
Of course, the articles describing this problem never choose to more-precisely identify the "Israeli" tourists (who are, in fact, probably not Jewish).
