Oh wow, this is a big question.
Let’s start out by saying that I am 47 years old, and I have a daughter who will be 18 in January. I’m not just out of my teens, I have a kidlet that’s almost out of HER teens (and it’s probably very funny watching us watch TW together).
I’ve been in fandom, in some way or another, since I was 12 years old. In the years before internet, in the years when in order to be “in fandom” you either contributed to fanzines or you went to conventions or you just hung out with your friends to do things. I started gaming when I was a teen, I read & collected comics, I wrote filk, and I wrote both original work and fanfic (except I had no idea I was writing fanfic, honestly).
What I’ve found is that fandom isn’t just about teens. While I’m often one of the oldest in the crowds I’m in online lately, I’m rarely THE oldest. Fandom is ageless, in my opinion. When I was a kid, I had friends who were as old as my parents (still do).
For face to face hobbies, like tabletop gaming, there are game shops and bookstores to meet folks who are like-minded. I basically keep finding my tribe, finding folks who like the same stuff. Fall in with other adults. I started in college; when I got to Union, I wasn’t ready to put away my hobbies. I went to the gaming group and made friends there. Through them, I made friends at RPI, and that’s where I ended up for grad school. And I also started hanging out online way back then (late 80s, seriously, not even joking) and I made friends online before it was considered normal to do so.
It’s about finding anchors. Talk to folks, don’t worry about age. I seriously love folks in fandom, love adults in fandom. Love that there are other people of all ages who love the same things, and want to flail about them.
Are you worried about being ostracized by fandom? If someone’s being an ass to you, they’re just not a good person, it has NOTHING to do with your age. If it’s out in the world that you’re worried about being ostracized, that’s a little different. Fandom has become more mainstream, more acceptable, but it’s not perfect yet. Folks DO understand that adults are fans now, at least, I think. I don’t go into it in detail, but my screensavers are various media, and I have art from fics hanging on the walls of my office.
Inside of fandom, some folks just want to pull people down. Trust me, fandom is full of folks who are over twenty, over thirty, over forty, and even over fifty. I’m planning on keeping on writing, well into my dotage, right up until the time I don’t have any more words. And when I’m older, I will be right there with the younger folks, encouraging them to keep loving what they love, and don’t apologize for it.
They call us fangirls because they belittle our fandom by making it childish. But it’s not childish. It’s just loving a thing, like some folks love sports. And like it says in Harry Potter, love is the strongest force in the world. So I encourage it.
Someone liked this today, and I reread it, and I’d just like to say that it’s a year and a half later (and I’m watching that teenage daughter angst about her 20th birthday approaching), and I still stand by all of this. Love what you love, and celebrate that love.
