No. For the most part I separate the author from their work. The exceptions would be non-fiction books. I will look up those authors to get an idea of how serious to take the topic they are writing about. There has only been one author I looked up to get personal incites about, Ayn Rand. The only reason I looked her up was first to find some redeeming quality or reason for your writing style and philosophy. Then it just turned into animosity ammo to argue against her proponents.
