I'm searching for examples of those silly things we fight over. You know: Kirk vs Picard, Gryffindor vs Slytherin, whether the toilet paper roll should hang over or under, or the ultimate superiority of Star Trek vs Star Wars. What stupid but strangely polarizing issues have you fought about in the last year??

EDIT: Ones I've already got:

Captain Kirk vs Captain Picard
Star Wars vs Star Trek
(or Gene Roddenberry vs George Lucas)
Dogs vs Cats
Over vs Under (toilet paper roll placement)
Mac vs PC
Gryffindor vs Slytherin
Ninja vs Pirate
Boxers vs Briefs
Leno vs Conan
X-Men vs Justice League
Dishwasher Wars:  Pre-Rinse vs No-Rinse
