Elizabeth Renzetti describing others as "entertainingly shrill" has to be the height of amusing irony. Although she does later find a better self-descriptor later in the article when she refers to herself as a "maladjusted weirdo". 

Opposing extremism is not a hate crime. And there IS one religion at this point in history whose extremist element is responsible BY FAR for the majority of terrorist atrocities committed daily. That's why it's being "singled out", because it's  unique in the sheer level of associated crimes committed by it's most extreme adherents compared to any of the other major religions! Wake up!

No one is entitled to commit hateful acts, such as the murders in Montreal. And there are already strong laws prohibiting such acts. But it is still the right of people to hold, and express, whatever opinions they choose. When you start trying to regulate thoughts, it's a dark, downward slope. One that Renzetti seems to shrug off and be surprised anyone would object to.
