I’ll address Duke real quick, because I actually like him and his enthusiasm, and I have no desire to run him off (as opposed to our friend Zach)
Duke: When I was in my early 20’s, I was put in a position of authority at my job over people 2, and even nearly 3 times my age. I did not get much respect from them. I had appropriate knowledge for my position, but I had not proven myself to them, and my age, in and of itself, was a problem.
This is real life, brother. You have to accept, at some point, that being a young kid, your advice will not be received well, and giving it will not serve you, nor the person you’re advising. It’s a tough pill for you to swallow, because you believe you are acting altruistically, and you are also convinced that your knowledge exceeds that of others. I am not going to tell you whether or not you are stupid, nor am I going to address how much you actually know, because that stuff doesn’t actually matter a whole lot in the big picture of advice-giving, as much as you want it to. You are not in a position of authority. You’ve made admirable games, but you’re still not where you need to be to give advice.
I DID what you’re doing when I was younger, and smaller. I thought I was in a position to give advice, because I’d read a bunch of books and articles, and felt I had a good handle on what should and should not be done in the gym. And it always irritated me that people weren’t receptive to it. Now, being on the other side, I get it. That’s what I"m trying to impart to you, and I’m hoping you will develop some empathy for the other side. You haven’t walked the walk yet, and for that reason, you will not get respect. Period. Put your nose to the grindstone for the next 5-10 years, develop an enviable physique, and then come back to what you’re trying to do now. EVEN THEN, most people won’t be receptive to your critiques, but you’ll at least be in a better position than you are now.
One last note that I think you haven’t considered. There is nothing wrong with getting hurt. Injuries are ok. You know all those things that you’re worried about other people doing in the gym? As far as risk and danger are concerned, those are going to be NOTHING compared to what, say, I am doing in the gym. Lifting 300 lbs atlas stones is a FAR more dangerous activity than having a shitty squat form, or bad ROM, with medium to light weights. We are all responsible for the risks we take, particularly as we get older. It will never, even be your right or place to give unsolicited advice to anyone, in any walk of life.
