Munira Mirza makes a great point about how fearmongering is used to stifle debate in Britain and concludes:
Controversial issues require heated debates, not conformity of opinion. Projecting the worst-case scenario of race riots can end up encouraging a form of self-censorship. If people are given scare stories about public reaction, they may be less likely to stick their head above the parapet. This allows ill-informed opinions to reign and prejudices to fester. We need to have a much more positive conception of free speech, particularly the kind that ruffles feathers and arouses passions. A healthy democracy can only work if people are not afraid to disagree, even if that means taking a not-very-gentle tone.
