I'm curious, why do you feel you can't express your interests if the subject matter has legitimate academic value?
For instance, the majority of comic books are c-grade pulp fiction trash, but that doesn't mean that works like Watchmen, Berserk, and Maus don't have literary value. I wouldn't share that with middle school students, of course, because they're not old enough for the material in question, but I've seen Alan Moore being taught in universities across the nation. You should be happy to mention games, comics, and other stories that have legitimate cultural value, because they're avant garde. They're pushing they're respective mediums forward as legitimate art (though comics seem pretty dead in the water these days).
If you can't discuss it with your colleagues for whatever reason, since middle school and high school are more opposed to free thinking then college, then try and form a sort of "literary group" of close friends. You can discuss the artistic value in games and other forms of alternative media. But don't be ashamed to enjoy what you enjoy.
OT: Yeah, I ignore fandoms. All of them. They tend to get really annoying really quick.
Well, depending on the topic, it's because of the fear of public perception.
One of the problems of being a teacher is that because you are supposed to be a "paragon of morality", you have to maintain a good reputation. Liking something that the general public sees as wrong can, at best get you branded as a weirdo, and at worst, lead to several very angry parents calling out for your head.
I gave an (admittedly hypothetical, but not far-fetched, given a lot of the quirks of working in this country) example several posts back, where a teacher would off-handedly mention anime, it gets back to the parents, whose only perception is "those dirty cartoons I once saw my son watching", which eventually explodes into "Teacher talks about porn in class."
And it's not discussing it with colleagues that's the major concern. It's the students you have to watch out for. With other teachers, it's more of a discretion thing: the ones who are roughly my age, I could probably talk openly about League of Legends or Warhammer 40k or XCOM. But with the senior teachers, I'd have to watch what I admit to liking, since they'd have some influence on whether I get re-hired next year or not.
EDIT: Also, high school (there's no middle school in this country. Not yet, at least) isn't opposed to free thinking. Not the modern ones, anyway. The problem is that political and social conservatism is de rigeur here in the Philippines, so teaching kids to be free thinkers (one of the 21st century skills we're supposed to focus on) is always going to be an uphill battle.
