I really hate that the rhetoric of liberty is perverted in the service of illiberal causes. And I hate this not just because of the hypocrisy of it. I hate this because now that the language of liberty is indeliably associated with those wishing to deny liberty to others, it is relatively simple for all who wish to deny liberty to others to argue that it is in fact those who wish to defend liberty who are in reality attempting to suppress it.
For example, it is well-known that the Ku Klux Klan would deny liberty to blacks, Jews, and Catholics, among others. Yet in rallying people to their cause, they speak of defending their freedoms. Now any who would defend liberty can be discounted as fellow travelers, tarred by association.
This rhetorical identification allows those who would expand their power at the expense of liberty greater discretion. You don’t really want to be like them, do you?
