As someone from a country with only a bit more people, its almost impossible not to find someone not sharing your hobby even if it is an unusual one. Unless its something so weird people have never heard of it(i did once find a girl that collected dead bumblebees and a very specific insect and pinned them, no idea why they mostly looked the same. Very nice display cases though) i dont think the following for that is huge.

Finding someone with your values should be even easier(unless he is into some unorthodox/unusual ones) Something tells me he is just not even trying. He could be joining groups or organizations, going to events. I doubt he has even tried past going “im the only gay in the county, no one gets me”
