"Just because he looks like a Jew don't mean he is one" would indicate what....Jews can be identified by their features? My perception is that Jews come in about as many shades and packages as Irishmen. Or is there a set of features that definitely stamp a person as a Jew, like the semitic caricatures concocted and publicized by the Nazis? Maybe there's no element of racial stereotyping evident in the quoted comments, but it sure strikes me that way.
