Yeah, that's about what I expected.
The fact that you think being good at a hobby makes it acceptable for you to treat others like shit is why so many people - myself included - don't give a fig what you've done in the hobby. Your immediate response to any sort of criticism, whether or not it has anything at all to do with bonsai, is to leap to a dick-measuring contest. Congratulations. You have older trees than I do, and you know more about keeping them in pots than I do. It's probably fortunate for you that they'll leave much more of a legacy of your time on this world than you as a person.
How many friends do you have, Al? Not sycophants attracted to your prestige, not people buttering you up to learn from you, not people who sometimes share a beer with you after you've done something for them, not people who simply tolerate your presence. How many actual friends do you have? If how you act here is any indication of who you are as a person, I'm pretty sure we both already know the answer, and it's a sad one. Attention-desperate narcissists tend to not have long-term, meaningful relationships.
There are plenty of bonsai artists who are better than you who can somehow manage to not to be complete asses. They even have a bit of humility. Maybe you should learn that particular skill from them... unless you're happy with your life the way it is. Given your age and the fact that I'm no doubt far from the first person to tell you something along these lines, you probably are - or you're too lazy to put the effort in at changing. Either way, it amounts to the same thing.
I'm not jealous of you, Al, nor do I hate you. If I cared enough about yet another internet-dwelling asshole, I'd pity you. I'm sure there's something sadder than a man old enough to be my grandfather acting like a preening, pissy teenager convinced his shit doesn't stink, but for the life of me I can't think of anything.
I've got a challenge for you, instead: Grow up. Get over yourself. It's decades overdue.
