&gt; It is far more likely that he raised suspicion by wearing a keffiyeh
&gt; a picture of Guido Menzio wearing a scraggly beard and keffiyeh combo.<p>He is not wearing a keffiyeh in that picture.  A keffiyeh is a square scarf that is worn on the head.<p>In that picture he is wearing a non-square (fringed) scarf, and around his neck.<p>Only a nut would look at that scarf and make the leap &quot;Yasser Arafat&quot; -&gt; &quot;Palestinian Liberation Organization&quot; -&gt; &quot;terrorist&quot; as you do.<p>TV cook Rachel Ray made an ad for Dunkin Donuts a few years ago, in which she wore a scarf around her neck.  The Trump-supporting type nutcases came out of the woodwork and said she was wearing the scarf to support the terrorists.  You can see a sample of it if you Google &quot;Dunkin Donuts&quot; &quot;Rachel Ray&quot; and &quot;keffiyeh&quot;.  Most of the articles are by people who appear on Fox News regularly.<p>Only a wack job makes the leap from a math professor who is presumably an American of Italian descent that wears a scarf to the scarf being a keffiyeh!  That Yasser Arafat wore!  Who was in the PLO!  Which is proscribed as terrorist!  By make the leap I mean make the leap like you did.
