Out of my entire friendgroup there's perhaps 2 people that are into any sports at all to the level of regularly watching it.

I think what you need is to see a therapist and to rethink your position in life a bit, because it seems very misanthropic without being based on reality. I'd wager that most people don't care about sports all that much, at least anecdotally.

You might invest some of that money into therapy instead, then.

It's perfectly possible to find friends who aren't into "sportsball", but it takes more than paying an entry fee so you're allowed to hang.

I strongly disagree with this.

A lot of us in the furry fandom have friends who are not furry. You would not believe the number of "normal" people who have seen pictures of my fursuit and thought it was cool. Everyone in my bible study thinks furry conventions look like fun but they would never attend a convention themselves.

And if your difference is not with identity or hobbies, significant number of our group are neurodivergent and/or LGBTQ+(whatever the acronym is today).

Despite what's happening currently, US culture has gotten less uptight about these things in the last three decades. With the internet people have a lot more exposure to things they wouldn't have seen before. And I believe, more accepting as a result.

Finding a friend can be difficult, but with the internet it is not impossible.

I don't watch sports and have plenty of friends. This sounds firmly like a you problem, I'm afraid.
