The atrocity of October 7 was an evil attack on Israel, but it may well have a much more widespread, insidious and malign influence on Canada and the West.

In a bizarre twist, the horrific barbarism of that day against the Jewish state has unleashed a wave of antisemitism and, indeed, a support for terrorism, that could affect us for generations.

Perhaps that hatred was in Canada all along, a corrosive undercurrent of antisemitism running deep and wide and dangerous. Now it is on display in the streets, in schools and on university campuses. Left-wingers, trade union leaders, academics, teachers and even politicians have been tainted with it.
