In my case, it was in the boating forum, had a southerner get bent out of shape over similar boats we were building in one case. The second was a pair of midwestern "EXPERT BOATERS" that didn't have a clue start giving bad advice and got all bent out of shape over me calling them on it. For some reason, they felt their <2 years of experience trumped my 30+ years experience, even though I was able to explain the what's, why's and how's that they couldn't figure out or understand when it comes to building and setting up a boat. Funny thing is that most of what makes a plane work are the same things that make a boat work.
