I consider myself pretty idealistic. I think the long-term success of humanity is pretty important, and spend a little time, now and then, imagining how it could go, and how to get from here to there. I'm not sure precisely what idealism is – I'm not so confused as to think things are perfect right now – but I figure general, cautious optimism, where the caution is drawn from an abundance of care that things go well, is in the right ballpark.
Every once in a while I'll be intrigued by the task of learning Esperanto. It's never been as serious as my other language learning efforts, but it's always been there, like a weirdly insistent buzz of possibility. Intriguing and annoying at the same time, this strange constructed language doesn't stay out of my thoughts for more than a year or so at a time.
And yet, I can't speak it. I find myself concerned with the strangely hippie-centered culture, and how they would judge me. I'm a pretty let-live type of guy, but I like capitalism, I have no ill judgment of oil executives, and have no desire for the world to have one peaceful government, or even one mega-culture – lots of options for everyone seems better.
Now, don't get me wrong, the Esperanto community has no reason to pander to me. Who am I to them? But I'd appreciate hearing more about international languages opening up new, efficient markets, for instance. The success of China (compared to India, for instance) has been accelerated by standardizing on one language and one unified-ish market, but their totalitarian control extends only to their own borders – volunteerism is something every human can appreciate.
But I think there's an unfortunate consequence of extremely small communities without much in the way of explicit cultures and ideologies: they become dominated by the people who take the time to speak. This is going to over-represent both extreme social justice-y types who confuse speaking about doing the right thing with doing it, and extreme alt-righters who I can't even begin to explain, except I bet they appreciate having an audience of less-skeptical language-learners merely meaning to practice reading comprehension. The nature of Esperanto gets more of the former than the latter, but not none of the latter, it's important to note.
I'm also interested in Esperanto as a social technology. Make something easier for me, build a community that lets me help make something easier for them too. Have a strong mutual-benefit society, or hyper-frequent high-quality meet-ups. As a young person: get some more young people. Maybe they need to figure out some weird enticing thing for us whippersnappers specifically so it's not a grey-hair-required country club (that might be the best case scenarios without more young people). With utter strangers, I mostly want to talk about silly things I heard online, too, and boy howdy can older people be weird with what they want to talk about. I love the Quakers, but chatting with some of those people after service got me concerned the human brain stops wanting to talk about interesting things as it ages.
Honestly, I'd recommend Esperantists organize around a really specific club and develop a hyper-specific culture from it, with strong rules for how to exclude bad actors. Without that, Esperanto will still have a culture – but not one many people would want to join.
