If you do not believe that with expansion the galaxies are speeding away from each other because of expansion then look up the simple single surface model of points on a balloon being blown up (and so expanding the surface) speeding away from each other, that is often given as an example.
Galaxies do not have high velocities against the cosmic background radiation because the microwave cosmic background is expanding too (hence why it has cooled so much from its origin at the time of the "Big Bang"). (EDIT: perhaps your difficulty in understanding what is being said is because you do not realize that point?).
If you believe anything other than the above then your belief is contrary to the current expansionary models. If you do believe that, then you have completely misunderstood what has been posted and so have been arguing against it in vain.
At this stage I give up with you.

Don't give up AnotherCat. Keep your eye on the spot on that balloon closest to you and you'll see that it isn't moving, even though the space between the spots is increasing. It's the same for every spot. None of them is moving but they're all getting farther apart, the more distant ones at a higher rate. The growing space between them makes the other spots
appear to be speeding away, while none of them is actually moving. Within its limits, the balloon is a good three dimensional analogy for four dimensional spacetime. Distant galaxies
appear to be speeding away because of the growth of space between us and them.
