What an excellent thread. I have considered starting such a post regarding trolls and newbies. I thought perhaps before they are allowed to post
they ought to have to look at a thread wherein the "truths we hold to be self evident , here" are outlined.
Each person has his own trajectory. Mine is rather long at 52 years of audio. I was fortunate in being able to take an electronics for scientists two year course, in about 1969. At that time I had about a ten year history of building electronic stuff (starting when I was about eight with a crystal radio). I built lots of things from kits and from scratch. So I had a very good background and all my pals and fellows would bring me their amps and receivers and whatever else to fix. In the mid seventies I worked in the industry for a few years. Even back then there were things that I thought smelled very bad. We are reaping the whirlwind of those bad smelling things , just as we are in politics in many many countries.
In politics
ad hominem attacks have become predominant. I try to avoid these wherever possible. They probably are a cause of the high rate of marriages breaking up. People don't know how to argue fairly and with decent manners. I am very often amazed at the poor manners people use online. (even here sometimes)
Sometimes the "audio system" is an object of worship, to be praised and showered with overpriced gifts to show ones devotion. Spensive speaker and power cables, trestles for same, special spikes to couple or uncouple to the floor and endless other things to show your devotion. You should never love something that can't love you back.
When I participate in a thead and someone clings to moronic ideas and responds with insults I withdraw from the thread. With or without (usually without) a parting shot and sometimes I even delete my posts. I am always 100% willing to help anyone that asks me for assistance or advice, but I also have very low tolerance for bad manners and ocassionally will call them out. I would prefer it was never necessary. Someone can be forgiven for being incorrect and even being strongly convinced they are correct. But it is possible to do so without being nasty. Sometimes it is difficult to strongly disagree with someone without it appearing to be mean or nasty.
I remember "back in the day" when PS audio had a preamp kit I was interested in but never bought. Then I returned to the audio hobby after about a 25 year absence and here is Paul McGowan holding court on You Tube. I don't like nor agree with many things he says. But even his detractors probably need to admit that he keeps it professional and not nasty. (I haven't watched him in a while so if I am wrong here please correct me) I find similar things with Steve Guttenberg. He doesn't say anything nasty that I have seen though , like Paul McGowan I consider him mainly a salesman. One could say that this "professionalism" might make it difficult for the "uninformed" to determine if they are being mislead. (PS,, Edit)
Hans Beekhuizen( sp?) is another. When I returned to active audiophilia I had a lot to catch up on, and like the aforementioned pair, it took me a while to catch on that he slings a lot of nonsense along with some correct info.
I have worked very hard over the years to build what I consider an excellent sound system. As well as to learn how to do it. It is hard to mind ones' manners when insulted by someone whose only qualifications are , they went to a high end store with a gold or platinum card and squandered a large quantity of their family treasure, with a charlatan. Some of these stores are like yacht stores. If you have to ask , you can't afford it. But we all know that kind of expenditure isn't necessary.
One of my other hobbies / activities is working on my lawn. I like to use power equipment and maintain it myself. There is a truly GREAT YouTube channel called "Taryl Fixes All" The guy has a large repair shop in Indianna south of Chicago. I think he must be filming everything he does. He also is hilarious. Taryl has a line which I love that he uses frequently. "It ain't th Space Shuttle. It's a lawn mower!" To paraphrase,
"It ain't the Space Shuttle. It's a RECORD PLAYER!"
