Why does it not suffice to use the dictionary definition of "rotation"
http://www.m-w.com/cgi-bin/dictionary?va=rotation
and of "generalize" (in the transitive sense)
http://www.m-w.com/cgi-bin/dictionary?va=generalize
especially definition 2a:
"to derive or induce (a general conception or principle) from particulars"
It won't do to claim that the rotation operator can't be generalized; spin
and isospin are well-known examples of generalized rotations.
