Is it wrong to like mammals the most?

I made a list of animals I thought were interesting or liked the most, and it turned out that the majority were mammals (elephant, tiger, lion, orca, manatee,hyrax) with some others (hammerhead shark, frogs, peregrine falcon). Then I realized how narrow-minded I was. Is it wrong to like mammals the most, and what is your favorite animal group (reptiles, amphibians, crustaceans, etc.)
