Just accept that everyone on here has their particular field of knowledge, and ignorance.
Problems arise with those who don't know that they dob't know and try to impose their misconceptions on everyone else.
We all have our opinions, with varying degrees of logical and factual justification.
My background is essentially internal combustion engines and vehicles, so my knowledge of electrics and electronics is limited. So, I don't pontificate on how to mend the control board on a mini lathe. (I can just about understand that a triode, or a simple transistor, modulates the current flowing through the device; but not understand in detail how it does it. )
When I see a question or comment from someone who is an obvious newbie, I try to be helpful, based on my knowledge and experience. Sometimes, there is a post from someone who knows, or thinks that they know, better If it is obvious that the logic stream is wrong, or unfounded, I will differ, if only to set the record straight.
There is no point in spending time and effort in trying to educate the bigots. Life is much too short to waste time on them. That probably makes me one!
Rightly or wrongly, we all have different opinions, based on our experiences.
As an ex Myford ML7 owner, I differ from many, in not worshipping at the shrine of Beeston. That is purely my opinion.
There are many others who show their expertise by producing superb work from similar machines.
I have cut a few gears, but would never claim to be an expert on gears, or even capable of producing very good ones.
Perhaps the real skill is in being able to differentiate the dross from the gold. (There is a vast amount of that on here, if only you can spot it. ) The ability to recognise successfully grows as we become more knowledgeable and experienced.
Some comments will disagree with your statements. Some of those will be valid, others will not!
Filtering the good from the bad is part of the learning process.
You never win 'em all!
