The word 'centrifugal' means RADIALLY OUTWARDS you silly old bugger.

There is a radially inward or CENTRIPETAL force on the shoe.

It is a RADIALLY OURWARD FORCE. It is CENTRIFUGAL.

Stupid argument. That kind of force is not related to the rotation. The radially outward ..or CENTRIFUGAL force the shoe exerts on the drum IS.
Why do you think the device is called a 'centrifugal clutch'?

You are really clueless. There is no 'absolute space'.
The centrifugal force is imaginary in the rotating frame. We all know that.
