Don't let other people stop you from sharing and enjoying you're interests. That being said, if someone doesn't seem receptive that might be a sign "to take 20 percent off" the top and find people who are. It's important to be around like minded people, and to give other people room to be themselves too.
When I was I young, I used to get obsessively interested things until I started realizing that other people started being less receptive to me, so I pulled a reverse uno and gradually started closeting myself inside myself until I pretty much lost my sense of personality and interest in other people. Not a healthy way to live by any means, and it's one of the reasons I'm so neuroticly quiet and disinterested in people that I can't even sustain basic, small-talk conversations anymore. That and other traumatizing factors in my life.
Expression (expression of interests, movies, games, music, art, literature, sports) is a necessary component of existence, it's just difficult, because not everyone will be receptive to it. I hate seeing other people's fire get put out like mine did.
Edit: in world religions class, I learned the word "heretic" essentially means "to choose." I think subcultures, whether on the internet or irl all have their "heretics." If your family likes sports and they look down on you for not participating in their sportish rituals (lol), you're the heretic in the room, the one who is different from the rest. If your dad and his dad and his dad's dad liked cars, and you don't you're the heretic of the familial line, the one who "chooses" if choose is the right word, to be different from the rest. No matter what culture you're apart of, it's always hard to be the one outside of the accepted norm.
