The qur'an itself isn't the greatest problem, my opinion.
As well as muslims can take a verse in the qur'an and despite anyone's imagination, succeed to convert it to a "scientific statement" and people believe, an islamic scholar can also 'translate' violent and extermist verses in the qur'an in absolutely anything, and common muslims believe, if that is indeed seems to be that islamic scholars' conviction. So the greatest problem is the man, not the book.
anyway, if islam had died soon after muhammud's death and only now had been discovered qur'anic texts, no one would have believed it and took it as the "dictated word of almighty Allah". Instead, people would have understood it as the foolish legends of Zeus and other greek gods.
Left alone, the qur'an means nothing. And if evil people existed, there would always be a doctrine and a text.
Moreover, if non-muslims ban the qur'an, it is a sign for muslims that they are right and that they are victimized, oppressed, persecuted, etc. in that place and cry it out everywhere.
