Walk down the street pretty much anywhere and you will be the standout. Just how it is. Sure, hang out at a hard core gym and frequency increases. Compete and train in the PL/OL circles. Go to a fitness expo or MMA fight, frequency increases. But reality is most of us belong to a small subset and I think a lot of interests including but also outside of this put us in multiple small subsets and that's where we find our niches and fun.
I come to forums or here because I largely have no one else interested in this stuff to interact with on my day to day. We have kids, jobs, I travel for work, running around like a mad man. These days I train at home alone and love my workout time. It's my break and personal slice of fun. I have plenty of other interests but this one I at least maintain as it's foundational to me and healthy enabling me to perform at all the others.
I think our frame of reference around ourselves and normalcy gets distorted. One of my friends who's not big/huge by standards here is probably 6'4" and 220 at 12%. He views himself as small because just about all of his lifter friends are bigger. Operative words are "lifter friends", it's like he's not even considering anyone else which is the overwhelming majority of people around him. He's hanging out with lifters and benchmarks himself only among them - people who've spent 30+ years in gyms, guys who've won regional, national, and world comps including holding a SHW world record. I made the point one day that he can walk around our city all day and likely be the biggest guy he sees out of hundreds of people. That's not small, his frame of reference is off. Apply it to golf, the scratch golfer hanging out with PGA Tour pros is the laggard but he's probably the best or among the very best golfers at his home club and people are wowed by him all the time. Same deal.
Interesting phenomenon though. I've spent some time pondering it.
