In 2007, she wrote a column titled "Not in my backyard, either" in which she criticized Hasidic Jews for not integrating into the neighbourhoods in which they live and for being "self-segregating" and "cult-like". In 2008, Kay criticized the behaviour of the Hasidim towards the Deputy Mayor of Richmond Hill, Ontario, Brenda Hogg, who attended the Menorah-lighting Hanukkah. Kay wrote that if the rabbis, whom she called "black hats", cannot observe "small courtesies" then they should "stay in their self-wrought ghettoes and eschew public life altogether". In her July 28, 2010 "National Post" article, Kay 2007 wrote about Jewish messianism, the theme of a 2007 Michael Chabon novel, "The Yiddish Policemen's Union", against the backdrop of the rise of the Haredi Judaism in 2010, an "extreme right wing ultra-Orthodox" that numbered approximately 1.3 million in 2010. Kay expressed concerns that could eventually dominate the Knesset—and "Jewish destiny".
