Q&A: Is it tolerant to force Tolerance?

Clark focused on making a tolerant society, even including people who have intolerant philosophies.  However, Clark points out that these groups must respect the neutral state and never resort to violent means.  Isn't ironic how the tolerant state must force tolerance and even resort to the ways it abhors in order to protect its neutral space?  It's just how the French Revolution needed tyranny and fear to create freedom.  Of course it is insensible to just allow the government to fall to a violent uprising, but how to ensure this protection doesn't became a form of censure and what happens to those who commit a 'crime of intolerance?'
