For starters, I think you need to look up the word “bachelor”. Half of these men do not fall into that category.
Secondly, Walder Frey should never be on this list. Ever. Nor should Grand Maester Pycelle.
Thirdly, why on earth are Jon Snow and Jaime Lannister so low down the list? They are two of the most attractive people in the show, plus they are two of the most interesting characters.
