I usually only share personally what is pertinent to the conversation. Nobody has shared they are a certified welder in this discussion that I have read. What is what I perceive "unfair" here is rather than others addressing IMO legit technical question(s)/concerns(S), for reasons that escapes me, the responses often go ad hominem, and to not expect then in fairness a pointed reply seems rather unfair, even if I have the ability to often do such and not sink to such crass immature levels. It suggests self-censorship on my part.
If my question was simply addressed, ignored, or mentioned they don't have an answer, the case is effectively "closed". It seems that is a bridge too far for some, and we have this game of everyone must get the last word in. The proof is right here in this thread for anyone caring enough to see it.
Your comment on field experience has a lot of merit. I personally try to stay in my lane on topics I have knowledge/experience of or wish gain additional insight.
Those that underestimate me or anyone else risk choosing the weaker position in making their points.
I'm here to gain further knowledge/insight, and when that becomes futile, I will find the door.
Thank you for your comment.
