There are people who believe that criticising Islam is Islamophobia, but such people are not liberals.
Genuine liberals, following the precepts of J S Mill’s “On Liberty”, believe in free speech. The only constraint on free speech, for Mill, is where it would result in serious harm to an individual other than the speaker. By harm, he did not mean hurt feelings or taking offence. A fortiori, he would not have included the taking of vicarious offence on behalf of someone else. Liberalism recognises no right not to be offended. If it did, then, in many cases, it would be necessary to ban speaking the truth.
Any religion is a belief system, and although the adherents of a religion may hold that their particular belief system embodies the truth, they have absolutely no right to demand that other people should believe or behave likewise.
If a religion, for example, forbids the eating of pork, adherents of that religion have no right to demand that non-adherents should abstain from pork. It may, historically, have been the case that such abstinence was justified by the hygiene standards of the day; it is so no longer, and if the only justification is an outdated religious prohibition, then it would be quite unreasonable to expect non-adherents of that religion to practice it.
Now, in describing the above problem, it might be argued that I have criticised Islam. In fact, I have also criticised Judaism, and indeed any other religion which prohibits the consumption of particular foodstuffs on the basis of historic rules. Does that criticism make me Islamophobic? Obviously not. I am not giving vent to irrational fear or dislike, I am offering rational grounds for no longer pursuing what I consider to be archaic practices. The adherents of a religion do not have to abide by what I think, any more than I have to abide by what they think.
In today’s politically-correct environment, an awful lot of people are prone to demand what they call “respect” for their point of view, but they then fail to reciprocate by displaying respect for the contrary or differing views of others. A common method of displaying that disrespect is to burn flags or damage memorials which are valued, or assumed to be valued, by their opponents. But that way lies vendetta, not reconciliation. That way lies the opposite of respect.
The “…ist” words or “…phobia” words are regularly employed as a device for preventing or ending discussion. However, since those words are intended as pejorative, those who use them appear to be reasoning, “I may criticise or abuse others, but if people criticise me, I will condemn them for being prejudiced”.
In condemning reasoned criticism of religions, we are in danger of allowing the introduction of a blasphemy law by the back door. It is not hateful to criticise. It is not disrespectful to criticise. Indeed, if a religion advocates violence or socially harmful behaviour, it is, at least arguably, a citizen’s duty to criticise it.
We should remember that stifling of dissent is not only a tool of the totalitarian, but also a barrier to progress and innovation. This world is not perfect. Anyone who believes that there is no more truth to be revealed than has already been revealed, or that no research or discoveries should be allowed that might lead people to doubt what they think they know already, is someone whose mind is closed and who does not wish for knowledge.
Such a person is epistemophobic. An irrational fear of knowledge is more of a threat to human progress than is criticism of any religion.
