 My personal view on this problem:
 galaxies are not held together by gravity and there is no need for gravity, because the galaxies are not rotating in their own frame of reference.
 It is OUR !!! impression from a remote position, that galaxies rotate.
 But seen from a comoving position from within that galaxy, the galaxies (of course) don't rotate.
 

Rotation is absolute. If a galaxy is rotating, that it is rotating can be detected either from within or without the galaxy.
