You are, of course, free to to believe what ever you want. My contention is that you are not applying those forces (shifting your wight) at the contact patch but rather at some point above them (your CoG) - so you are inducing a torque to the bike. Even if some of that torque is momentarily absorbed by tire flexion, eventually those forces have to equalize. There are after all laws about such things. ;-)
At any rate all of this is opinion and not science. Neither of us can prove our points without the science. So I'm sure we can agree to disagree.
