Last week, police arrested Shahid Hussain, 39, who they say went on an antisemitic crime spree, spray-painting swastikas on two synagogues and two high schools in Chicago’s West Rogers Park on Jan. 30.

Rabbi Levi Notik of the F.R.E.E. Synagogue told Fox News Digital on Tuesday that in the wake of those incidents, "our message is that we have to add in kindness and goodness and be positive."

"We are not going to be scared. We are going to stand strong, we’ll get through this," Notik said. "Judaism’s antidote to hate is love and our solution to darkness is light and our remedy to evil is good."
