Why do liberals think free speech only goes one way? Why is only their speech protected? How do they justify this to themselves? In my experience, it’s often because they see themselves as believing the right things, and so believe that the field of acceptable opinions has them at its center, not at the left-most fringe. As a result, all conservatives and worse are in the unacceptable part of the spectrum. Free speech shouldn’t really protect all speech, just that speech which falls within the acceptable range. At any rate, not anything that’s likely to change soon.
