Silly me, of course not, that would speed it up.NoCould the earth be slowed down, by deploying massive parachutes on windy days, from the tops of high buildings?
depends on direction
correct direction then yes
correct direction then yes

When you're in a plane flying high (Oh oh, some cracks coming after that remark) you don't feel as though you are travelling relative to your immediate surrounding, i.e. the plane. You only recognise that you are travelling by reference to the more distant objects. Ergo, the speed of the world spinning, orbiting, etc is a similar analogy.

No it can't.
The earth is a closed system in a vacuum, and the winds are part of that system.
Otherwise Hurricanes could affect the earth's rotational speed.
If we were not in a vacuum, that would be another matter.
If you had a lever long enough you could move the earth

not without a fulcrum strong enough
Aircraft navigation uses the earths speed of rotation for a all of their longhaul routes,and seldom fly in a straight line because what your aiming at ain't going to be there 15 mins later They tend to fly in parabolas and usually get it right

I refute the whole question, since noone has yet to define what point they are considering as being "stationary" in the first place.
The fact that space is a vacuum is of no relevance to this. For every action there is an equal and opposite reaction. That's how rockets work in space. If the wind was constantly blowing the flagpoles against the rotation of the earth it must have some affect. Even though the atmosphere spins in harmony with the earth, which according to coljack means that at the equator the atmosphere is spinning at 1037 mph, if you had a 50 mph wind against rotation it would then be spinning at 987mph. Which would then be slower than the earths rotation and must create a little drag.

But in order for that wind to be blowing in any particular direction, there must already have been a force in an equal and opposite direction to cause it change from a being in a state of uniform motion, which will have counterbalanced and subsequent effect

Correct, wind systems are effectively circular, and any effect you thought would occur is cancelled out.
