I don't think anyone is flat out refusing advice and tips. What many are not wanting to do is have a newb constantly asking for help and not having done any homework themselves. Fact of the matter is, one can only be successful in this hobby, in my opinion, if they want to learn what to do by themselves. My own father didn't give me much advice when I got into the hobby. Well, he would raise his voice at me while on the way home if that counts.
Other than that my dad never helped me learn the hobby, because he realized I was 1) gonna give up on the hobby because I couldn't figure it out, or 2) figure it out by some means and get good and flourish. I eventually got good at it by learning from my experience, and using the internet. Point I am trying to make is, if you truly want to get good at this hobby, and someday possibly great, don't expect others to teach you everything, just learn by yourselves. By all means, ask for help, but don't eexpect all the answers to be given to you.
Now, the question is, would I teach a newb. Well, I have had a few experiences with newbs. The first was with a 7 yr old that walked up to me with a cheap BH while I was hunting at a park. He pretty much asked me to find targets for him. I dug one target and gave it to him, and then his mom called for him. This, I feel was an experience that is close to what the OP is talking about. And, yes, I know, what could I expect from a little boy. But still, I did not know him, so there is only so much I could have taught him even if I had wanted to. Another thing to keep in mind is that I have never used a BH before, so honestly, teaching him how to use his BH would have been like teaching myself how to use it. If a grown man or woman asked me to do this, I would honestly think " what, are you crazy? how about coming to the table with a little bit of experience and not just asking for a handout?
The second experience I had with a newb was with my dads boss. He had recently bought a gti 2500 and had absolutely no idea on what to do or how to use it. I doubt he even read the manual or watched the dvd. He didnt even bring a good digging tool. Didn't bother to read online. The problem I noticed with him was that when mding he always held the pp button. Literally never let it go when swinging. I tried to tell him this, but he being 30 some yrs older than me, ignored my advice to not hold the pp button all the time, but only when you are over a target. He didn't do it rudely, but I quickly realized he wasn't going to listen to me. So, do what you want I thought.
My third encounter with a newb was my own younger cousin, and this is an ongoing problem I am having with him. He doesn' t ask me for advice, but when I try and tell him his holes are too big or that he must always pick up trash, he gives me sh@t. I don't do it rudely, just point these things out t him. If it weren't for the fact that I knew he would go and whine to his mom, I would tell him to sell his detector and leave the hobby. I HATE disrespect when I am trying to help someone.
Hope this doesn't sound like a rant, but then again it probably is.
