Yes because "Who's your favorite character?" Is a real tough question that only mega-nerds would be able to answer.

"What's your favorite song by [band you claim to be into]?" Such deep knowledge is required to answer. It's not that the reason you picked the shirt is that it fit an image you were trying to convey, it's that requiring you to remember anything about one of your favorite songs is an unsolicited gatekeeping test, and not an effort to introduce a topic you feel confident in to start a conversation.

"Do you like Shonen anime?" Shonen? This is obviously an attempt to introduce obscure foreign language jargon in an attempt make me look foolish, and stroke your nerd ego. Not everyone can spend thousands of hours learning Japanese, and this is definitely not a term in common use by the English community and a basic classification that every fan will know if they've done even the most basic legwork to seek out shows they like.
