The Left is conducting nothing less than a concerted attack on free speech.
As Steyn points out, The examples above are ever-shrinking Dantean circles of Tolerance: At Galway, the dissenting opinion was silenced by grunting thugs screaming four-letter words. At Mozilla, the chairwoman is far more housetrained: she issued a nice press release all about (per Miss Alcorn) striking a balance between freedom of speech and ‘equality’, and how the best way to ‘support’ a ‘culture’ of ‘diversity’ and ‘inclusiveness’ is by firing anyone who dissents from the mandatory groupthink. At the House of Commons they’re moving to the next stage: in an ‘inclusive culture’ ever more comfortable with narrower bounds of public discourse, it seems entirely natural that the next step should be for dissenting voices to require state permission to speak.
In short, the Left supports free speech only so long as it fits the current leftist ideals of political correctness. Anyone who dares dissent from the leftist line is a heretic to be silenced, if not outright burned at the stake.
