To some extent I agree with you, though I do think the Church needs to rebut some of these charges. The problem that the Church is faced with today is that the majority of the population gets its information from popular culture. We have seen the damage this can cause, when most young people get their news from John Stewart.
The problem with the Dan Brown novels is that they are clever enough that some people assume there must be some truth there. In fact there is none. There is no evidence to substantiate a single thing about Magdalene or book burnings, or Church consiracies. All of it is 100% made up. But some of it does sound plausible. The result is that at least 1/3 of the population thinks that at least some of this is true. This is unacceptable. I wouldn't insist that anyone become a Christian, but at the same time I have a problem with someone believing outright lies. Its no different from believing in a 9/11 conspiracy.
Are you saying that the Catholic church or its officials never burned books?
