Ouch, my brain. Just stop. Please. I can't take all this stupid in one post. At least spread it out over 4 or 5.Not really. If they're designed and tempered right they shouldn't be flexing a bit, at least nowhere in the same order of magnitude as a rotating/sliding interface. Sometimes they do though in a poor/weak design. Other times from fatigue.
Seriously folks, it's not even worth getting into link or pivot geometry as dude's fundamentals are so far wrong, it's like arguing baseball stats with a guy who thinks you hit the ball back and forth over a net.
