This 'liberal permissivism', sneer quotes times two, is neither liberal nor permissive; it is not liberal because it is supported and orchestrated by people whose mindset is anything but liberal (the term originally meaning free-spirited), it is not permissive because it seems solely pemissive towards people and activities that the so-called liberals seem to approve of, it is hostile to those that they do not (meaning conservatives, republicans, libertarians, constitutionalists, and anyone that are usually derided using x-ist or y-phobes).

Or to put it another way - 'liberals' broadly seem to be enamoured to vices, destructive, belligerent behaviors and things that most liberals of the past would find deeply il-liberal.
