Forum:Plot Hole?

Tom Riddle is a half blood so how is he able to seperate himself from his own persicution? It seems that this is a large oversight in the world of Harry Potter. I believe it says that his father was a muggle thus making him a half blood. If that is the case then he might be the heir of slytherin but he is no better than Hermione in the eye's of pure-bloods like the Malfoys   206.74.42.69 05:53, October 14, 2009 (UTC)James Brown
