sadly I agree with you, I used to be more involved with helping people and educating people, but I've literally learned the hard way, that sometimes the saying "no good deed, goes unpunished" is actually true, sometimes...
the EXACT same thing happened with my career in the auto industry, I used to help SO many people out, free of charge, but in the end it sadly goes either unappreciated or simply abused.
an example would be fixing an obvious problem, on someones car prior to an emissions test, and still having it fail due to a totally different issue, then all of a sudden the customer says "well my car passed last time I smogged it, what did you do?"
that's where I subtract the urge for physical violence and calmly tell them EVERY car passed last time, that's how you got it registered....
that's like blaming the doctor for telling you that you have cancer, because last time you had a physical you DIDN"T have cancer....
hmm after reading this I kinda sound jaded. I'm not, I love life, just learned some shit the hard way
I've also noticed that a lot of potsmokers/growers are somewhat introverted anyways, kinda loners to begin with. Could just be the ones I know... But I know a few growers
