They were expected to toss out the hurt feelings stuff, and they did.
They were also expected (by sane people) to preserve non-criminal prohibitions against actual hate, and they did that too:
Using expression that exposes the group to hatred, hate speech seeks to delegitimize group members in the eyes of the majority, reducing their social standing and acceptance within society. Hate speech, therefore, rises beyond causing distress to individual group members. It can have a societal impact. Hate speech lays the groundwork for later, broad attacks on vulnerable groups that can range from discrimination, to ostracism, segregation, deportation, violence and, in the most extreme cases, to genocide.
Hate speech also impacts on a protected group’s ability to respond to the substantive ideas under debate, thereby placing a serious barrier to their full participation in our democracy.”
Good balance, good decision. A uniquely Canadian compromise. Bravo, Supremes.
