I was involved with the litigation about the constitutionality of that provision. I intervened for B'nai Brith in the case of Keegstra, where it was declared constitutional in the courts, by four to three.
I acknowledge that there is a constitutional risk. If you remove any of the defences, it becomes subject to constitutional challenge again, and it was borderline in terms of constitutional acceptance.
My own view is that the environment has changed so substantially and you see so much incitement that is religious based and leads to extremely violent acts that the removal of that defence, in spite of the risk, would mean that the provision could still withstand a constitutional challenge.
