Gotcha. It's ok to use your small group to characterize Islam, but it's not ok to use other small groups to characterize Islam.
That's because, in the most general case possible, all critics of islam can only project their huge biases in their assessment of islam in order to dominate and discriminate the poor muslims whilst Relativists are always automatic winners even if allegedly there is no truth
That we can actually at least approach the truth in the direction totally opposed to that indicated by postmodernist ramblings is of supreme indifference (actually without discriminating anyone, advocating the existence of a single secular law, not also sharia or for that matter something else religious, and criticizing the tenets of islam is not discrimination).
I don't think is a fluke that no muslim in the islamic world, even in the West, can write freely about the possibility that for example maybe the Quran is not perfect and Muhammad deeds not always without blemish*. Liberal muslims do exist (a minority, especially in the West) but at the moment the destiny of islam is definitely in the hands of very reactionary forces (making very probable that the foreseeable future will be the same).
Finally the curious fact is that the apologists of islam, usually very hostile to fundamentalist Christianity and its claim that the Bible is the inerrant word of God, make special pleading in the case of islam (why don't just leave the poor muslims with their innocent belief that the Quran is perfect?).
I'm afraid history proves plenty that it was exactly the move outside the incorrigibility of the holy book which strongly catalysed Modernity by extending greatly the existing secular spaces inside Christian societies (created after the rehabilitation of Reason in the 13th century and the papal reforms at the beginning of the 2 millennium CE; islam never had them in the Middle Ages by the way, even now they are extremely small).
My view is that we are not heading in the right direction, with plenty of good reasons, but this is just my view. The decisions belong ultimately to us all and I know to respect democratic rules. What I will always reject is the attempt to silence legitimate directions of research via 'brute force' (calling names, labelled automatically 'islamophob', warned, censored and so on) how the so called 'western progressives' are doing these days (honestly I would not talk so much about islam, there are better things to do, had not been confronted quite often with these fraudulent attempts to silence me).
*a muslim in Pakistan hit the nail
“Salman Rushdie speaks for me. Mine is a voice that has not yet found expression in newspaper columns, it is the voice of those who are born Muslims but wish to recant in adulthood, yet are not permitted to, on pain of death. Someone who does not live in an Islamic society cannot imagine the sanctions – both self-imposed and external – that militate against expressing religious disbelief. ‘I don’t believe in God’ is an impossible public utterance, even among family and friends. So we hold our tongues, those of us who doubt”.
