This makes zero sense whatsoever. Either she assumed all Muslims are raging, foaming-at-the-mouth anti-Semites who would melt at the sight of a Magen David or she's just one of those AIPAC-ers who thinks Israel is the 51st and most important state in the US.
Also, note how SHE used ISRAEL as the red cloth. There are so many things Jewish she could have put out. For that matter, the same star you can find on many objects that are not an Israeli flag - she did not think of anything else. That, actually, is a good reference for that thread about the fired professor on this board
