The idea that adults shouldn’t be allowed in fandom spaces and that it’s inherently creepy for them to be involved in fandoms at all is one that needs to die.
You’re never too old to be a fan of something, you’re never too old to participate in fandoms, and you are not obligated to stop participating in said fandoms once you reach some arbitrary age that fandom newcomers has somehow decided is the age limit for participating in fandoms.
This is especially aggravating for fandoms based on established franchises that are decades old. Voltron (34 years, 37 if you count GoLion), Star Trek (52 years), Star Wars (41 years), Doctor Who (55 years), these fandoms have been around for a long, long time. Who do you think started these fandoms in the first place?
It’s absolutely mindblowing to me that there seems to be this huge push to force “old people” out of fandoms, especially when they have been participating in said fandom for longer than the people trying to push them out.
I’ve even been seeing this with newer fandoms, like Danny Phantom (14 years), Harry Potter (21 years) and Sonic the Hedgehog (27 years). Most of the adults in these fandoms grew up with those respective franchises, and they shouldn’t be expected to just drop them like a rock the second they become “too old”.
Even if adults are joining new fandoms… so what? There is no maximum age limit on being a fan of something. Who are you to decide who is and isn’t allowed to participate in a fandom?
