We might not all agree on the value of free speech, and those who do might not do so for the same reasons.
True liberalism, which is so much at the heart of the Canadian Parliamentary Democratic system, is something Catholics should promote, even if it isn't the best of all possible political arrangements. It is the best given that we are who we are: sinful, profoundly, irredeemably.
True liberals believe that freedom is good because people are good. I believe freedom is good because people are bad. According to my reasoning, the best way to offer resistance to the worst of us: Putin, homosexualists, abortionists, is to limit their power. We do this by giving no group carte blanche immunity from criticism and debate.

Check out LifeSite's long awaited statement vs. Fr. Gravel here.
