Very realistic.  It is very common that one user asks another "I am
having this and that problem, it does not work here" and then the
other user comes over, uses su in an xterm to get into his own
account, picks the necessary information, does a copy&paste job or
whatever else, and logs out again.

For this kind of one user helping out another, su is very common.  And
I think it is prohibiting _this_ sort of cooperation is what the
"fascist" label is about.
