These talks don't feel normal to everyone, that's the whole point. Your barista was confused because it's a weird thing to argue about in public. The fun part is making everyday places strange for a minute. You get used to your own weird interests, but regular people haven't. Their reaction is the best bit, not just how normal it feels to you.
