Unless you'd be admitting to something illegal and immoral like touching kids inappropriately, and the friendship is over just because you aren't agreeing 1:1 on everything ("ew, you like MLP? We can't be friends") then there wasn't a whole lot of friendship to start with.
Enjoy whatever gives your life some whimsy. Be as true to yourself as you dare. Be free from other people's judgement. Believe me when I say that it's better to live in solitude, enjoying harmless things that hurts literally no one in the comfort of your own home than to be "popular" and hiding your true self.
If you wanna be a furry with a fursuit, go for it. If you want to hold hands with another woman, go for it. If you want to enjoy Bluey, go for it.
I get it, I really do. I would have a hard time putting a lid on the things that bring me joy in exchange for someone elses company. I don't tell the whole world about my anime plastic crap because the world doesn't need to know (ironic statement, I know) but it's not because I'm ashamed, it's because it's none of their business. But if I go join the other nerds in the local game store or comic book store, they would understand and we could share pictures of how we display our collections etc.
