I don't know anyone who has a problem with books that contain a dash of fantasy, or indeed, nothing but fantasy. A fantasy book with dragons is enjoyable. A book that claimed that dragons really existed historically and were instrumental in William the Conqueror's victory at the Battle of Hastings is not enjoyable, it's just weird. ASoIaF (and Martin) is quite clear that his dragons are fantasy, so they're unobjectionable. The problem is that Martin has been equally clear that he intends some other elements of the world to have been historically accurate.
