You were called out for saying that your "engineering knowledge and actual listening experience have not lined up".
That sounds like a fair statement. You didn't claim to be an engineer, and besides you don’t have to be one to have engineering knowledge, just like you don’t have to be an attorney to have legal knowledge. Just try and get sued!
Anyway, you were nice enough to dignify that pompous nonsense with a serious answer. I wouldn’t have. Maybe I’m not nice.
