Morally, speech is a privilege. That is, speech is not morally neutral, and since there is no moral right to commit evil there is no moral right to free speech. Materially evil speech has no privileges. (Note that this is a moral point, not a political point).
A person who refuses to unequivocally concede that cutting a living four-month fetus to pieces in a woman's womb is an immoral act of murder has no standing to speak on the subject of abortion. He may engage in all sorts of casuistry about ectopic pregnancies and difficult scenarios for pregnant women; he may be genuinely conflicted in his own subjective interior intellection; he may, indeed, be in need of apologetical help in order to see the error of his ways. But his speech on the subject is the banging of a gong, emptiness poured into the void.
Same with the subject of torture, for someone unwilling to concede that waterboarding KSM was unequivocally immoral torture. [Note: I've retracted "and a war crime", which I had originally written - Z]
