Guardians of free speech should be consistent with their values. Not just when it suits them, and not just when the speech is something you agree with. In-fact, most the time, free speech advocacy is about defending the right for people to voice and express, opinions, which are starkly different and even opposite to that of your own.
The first place to defend freedom therefore, is the first place it is denied.
It does no good to fight brown shirts, with brown shirt tactics.
In Germany, a "Nazi Grandma" has been denied being released for denying the Holocaust. She is 93.
No good has been done here, the lack of respect for the ethics of free speech that would send a 93 year old woman to prison for her opinions, no matter how wrong or vile, should be considered a universal afront to fundamental liberal values.
