Slightly Orwellian Newspeak
Although I agree that slacktivism is socially rampant, both for the individual and in our economy; a more meaningful term is cognitive dissonance. But again as in 1984, adding more words to our language by copying distinct definitions of words, applying the new definitions to newly coined words, is the same as completely erasing the words from all thought, especially if those words reflect the contradictions in the person's thoughts.
