I'm sorry you feel that way - but the responses aren't really bad natured. They're just ... weary and exasperated. Was it @sergeauckland who said it's like yet another someone coming on a fairly advanced aeronautics forum, and saying, hey guys, I can flap my arms and fly?
The "demands" for "test labs in their living rooms" are a way of saying, no, you can't flap your arms and fly, because if you tried, you'd fail.
There are plenty of other forums where you can get together and talk feverish fantasy. We're not exactly depriving anyone of their human rights in preferring mature discussion in this one rare place.
Again, anyone “weary and exasperated” needs to simply not respond.
Why do members of this board feel they are entitled to treat others in this manner, which you may not perceive as disrespectful and uninviting but quite many clearly do? Why is a new member asking an innocuous question or presenting an opinion not deserving of a tiny bit of patience?
I feel like this is a very important point to discuss, and wonder where @BDWoody and @amirm might stand? I simply cannot imagine this type of reaction to new members has any place here...
