This is another excuse that the Captain Beatty gives to Montag for why destroying books is good for the society. According to him, any person can potentially be offended by a subject, also he argues that all books are better off destroyed than allowed to incite anger. Captain Beatty uses an example of a book and linking it tobacco and cancer. Something curious is that he shows the benefit of destroying information about lung cancer to keep cigarette companies happy, but there are risks that we can see since people will be less informed of what smoking can do.
Hope this helps.
