Physics isn't a matter of opinion
I've only been flying 4 years but I do know Physics, having done a PhD in the subject and postdoctoral research beyond that. Even though I'm from the UK, I'm with the Americans on this one: there is absolutely no way that an aircraft flying in a uniform wind (ie no wind shear or gusts) can respond differently from one flying in a windless sky (neglecting tiny effects due to the rotation of the earth). In particular its airspeed will be the same function of attitude and power in both cases. All inertial frames of reference are equivalent - this is one of the two founding principles of Special Relativity so if you disagree then you'll need to take it up with Einstein!
I'd hate to think of someone stalling in an upwind turn because they were confident their airspeed was going to increase....
