(Spoiler Main) What fan theory do you hate ?

I hate the theory that Tyrion is not Tywins son because I always felt that it cheapened their relationship, because by reading Tyrions chapters it is obvious that Tyrion is Tywin in anything and everything. From their cunning wit, shrewdness, their taste in whores, their ruthlessness and all that.

The wonderful scene that Genna had with Jaime would be rendered null if this theory was correct.
