Cedarhurst, L.I.: In your latest piece of half-truths and drivel, you state that Matthew Mahrer is a Jew, the grandson on his father’s side of a man who is a Holocaust survivor. Had you taken the time to Google what defines one’s Jewish lineage, it would have informed you that Judaism is passed through the mother-to-child process. Unless his mother and her mother before her were Jewish, Mahrer definitely is not.
