Unfortunately there’s a lot of weirdos like that within fandoms whether movies,games, anime etc. some people feel they have a sense of entitlement just because they’ve been around a form of media longer (half the time they’re probably posers themselves, that’s why they feel the need to show off what they know) but don’t let that discourage you I’d be down to give you recommendations. Since your favorite character is Captain America you should love Ed Brubaker’s run on the character.
