"You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true,
And unafraid of toil"
Okay so hear me out: While Steve Rogers is all about courage, that's not his defining trait. It's his passion for justice. His determination to keep going, keep fighting, no matter what happens. He is absolutely brave, but that's not what he values. It's loyalty and hard work. I get the argument for Griffindor, Ravenclaw, and even Slytherin (he's absolutely cunning and ambitious), but he'll always be a fellow Hufflepuff to me.
