If the earth, and all the stars are all accelerating at a constant 9.81 ms^-2, how do you explain red shift? or are the stars accelerating at more than 9.81ms^-2?

If you've never personally observed redshift, there's no need to explain it, as it could just be claims of the conspiracy.

Have you ever personally observed evidence that starlight is redshifted?

yes, that is why certain stars look blue or red when you look at them with a amateur telescope

No, that's due to the temperature the stars are. Cooler stars are redish, and hotter stars are bluish.

And even if so, the stars could be going away from us, just like how an airplane can go up in the air and “defy gravity”, the stars can, at least partially, rendering it to accelerate faster.

That would be the red-shift you would observe.
