Gatekeeping is incredibly important if you want to keep your hobby alive. There are tons of examples of hobbies being taken over and ruined by tourists. And before you say "ignore them", tell that to mangaka, illustrators, animators, vocaloid producers, etc that get harassed on twitter by legions of idiots that only discovered Japanese entertainment in the last 5 years because of covid. We have losers like the people I was talking to that have crybaby fits because tropes that have been around for decades offend their western sensibilities. And there are companies that listen to them because they're loud on social media. So no. You're wrong on every level. Gatekeep as hard as humanly possible at every opportunity unless you want manga/anime/LNs, etc to just become as sanitized and boring as western media.Gatekeeping is probably one of the stupidest things that exist. Only reason people gatekeep is because it makes them feel more special. If you actually enjoy and likes something, gatekeeping it is about as unreasonable as it gets. Things you enjoy and are passionate about are to be shared, not to be kept for yourself.
