Your graps of facts is tenuous. Not a single one of YOUR comments has been troll rated, and definitely not by me. I NEVER EVER troll rate someone I'm discussing with. MY comments, including this one again, have been repeatedly trollrated by you.

I don't doubt your credentials, I just say that you have not used them to provide the kinds of arguments that you should be able to muster easily, thus the assertion that your claims are 'unsubtantiated'. With your knowledge, backing what you say with hard facts should be easy enough, and yet you keep on doing it.

I have zero mechanical engineering competence, beyond a decent education in maths and physics. I have provided the kinds of backing for my assertions that I could, i.e. pictures that I googled.

I was the only one to call you mindless; several others encouraged you, so it's not like there's a nasty cabal against you. Yet you chose never to respond with arguments, instead reverting to feeling insulted.

I feel sorry for you.
