this post is bad and you should feel bad for posting such a bad post.
there's a difference between casually playing video games or watching tv and doing these things as a hobby. weebs aren't weebs because they watch an anime when someone tells them too, they're weebs because they watch all of them and tell other people which to skip (all anime) and which to watch (literally no anime). and the same thing can be said of "GAMERS" and casuals, or of people who watch tv casually (most people) and the bottom of the barrel trash of humanity (weebs).
really, most people don't have hobbies. they do a variety of stuff casually depending on how they feel that day. one day maybe they want to play some Overwatch, maybe the next they want to watch some Game of Thrones, and maybe the next they want to read some Stephen King. it's not their hobby, it's a way to pass the time until they die, and they're doing it not because they have a passion for the things that they're doing, but instead because they're scared of being bored.
if someone has something they're really passionate about and they spend all their free time doing that thing, or talking about that thing with other people who are really passionate about that thing, then why shouldn't they identify themselves with that thing? what else should they identify themselves with, what's between their legs? what they wish were between their legs? their skin color? how much they hate other people's skin color? if that's what a person is really passionate about then fine, but you shouldn't tell other people it's wrong to identify with their hobby.
what you've done is confuse casuals with actual hobbyists (probably intentionally in order to get some retard like me to spend 20 minutes writing a response, but whatever), and in doing so demonstrated a total lack of understanding of the mindset of either. the casual is uninterested in any aspect of a thing, other than how that thing can entertain them, be it television, music, video games, books, or anything in between. and all people are casually interested in most things. no person has the time or energy to have every hobby, and so they either find some area that they really enjoy and decide to invest a lot of their free time into, or do what most people do, and spend their time simply consuming the media produced expressly for casuals.
and any given person can be in either of these states at any given time, hobbies don't necessarily have to be all-consuming life-long commitments, but instead might last a couple of weeks to several years, or even a lifetime depending on how committed a person is. and this might be further influenced by the changing culture around a person, or their own changing financial situation, or any number of other factors that might change a person's interest in some area which they previously considered their hobby.
