Does anyone else feel embarrassed to talk about their interests?

I feel very embarrassed to talk about my special interest or my hyperfixations with other people, especially neurotypicals. Every time I feel comfortable to speak about my special interests, I talk a lot because I feel really excited and I want to share all my knowledge and opinions on the subject; but sometimes I think my interests are unimportant and I'm just being inconvenient. Most of the time, when someone finds out I'm autistic and asks what my special interests are, I just say the most superficial thing ever because I'm afraid they'll think my interests are stupid or think I'm "obsessed. For example: A girl in my class knew I'm autistic and asked me what was my special interest, and I said it's music, when in fact I like a really specific genre and bands. I didn't say objectively because I thought she would get bothered and think I was weird for knowing too much, as they usually say.

Even when I'm talking to someone who likes the same things as me, I feel like they are a "casual enjoyer" while I'm "deranged", and they'll think I'm a creep or something. It's hard to explain to neurotypicals how special interests and hyperfixations work and why they are important so many neurodivergent people. Of course, some of my friends (and my mom) understand me and I don't make fun of me because of what a like, but I still hesitate to talk to them about it.

TL;DR: Am I the only one who feels that way? As if sharing your interests is annoying and weird to others??
