I do not think that it is animosity, perhaps more frustration. In the beginning the board seemed to have a loyal group of advanced builders who shared really good information gained through years and years of experimentation, trial and error. thankfully some are still here, some are not. The overall membership seemed to be well past entry level. Then the flood gates opened and anyone who wanted to assemble any assortment of parts into something that would shoot started asking questions. These people did no research read no books and assumed that the old experienced builders were here to serve them. Guys would respond like "We discussed why you should not electric arc weld two pieces of tubing together to make a barrel a couple of months ago, please make a search." The questioner than would come back with something like "Why don't you provide a link." I get the feeling that some what to be spoon fed everything. I have had new builders to my shop, and they basically wanted me to build their gun for them while they watched, drank my coffee and ate my wife's cookies etc. I think it is just another symptom of the welfare state that our country has slipped into (but that may be political)
Buy some gun building books, try to solve your own problems, do the research, check to see if the topic has already been discussed ( yes, vinegar stain and a million moose milk recipes are there). If you have a problem (we all do beginner to advanced) throw it out there and say what you have already tried, don't ask something like what size drill bit do I use to get a 1/4" hole.(it was asked). I have gotten to the point that I answer some questions w/ a personal message to the person to avoid getting a dozen other questions, perhaps I deal better one on one.
Value the resource you have here before you lose it. I started my bun building with a $9.95 15/16 32" 45cal. barrel from P & S sales and a salvaged shotgun lock and a couple of rough castings from Dixie along with McCorys little book. I had to learn everything in the school of hard knocks and what I could glean from books when I could afford them. No one on this board owes you anything. they give of their knowledge freely. Remember the time these guys spend answering your questions is time they are not spending in their shop, they would like to see the sport flourish and see you succeed. If they are good they probably have a backlog of 1-3 years, so they are not trying to sell their product they are GIVING their knowledge to you freely, don't abuse it.
Now I will have a second cup of coffee and get to work.
