Expression of loyalty to party or tribe means exactly what it is, i.e.
that person has reasons to express loyalty. That doesn't automatically
mean that person is really loyal, belongs to the tribe, shares party's
ideals or anything else at all.
If person's particular activity doesn't make any sense for you
apart from same person promoting his/her importance, then it's
either because you don't see the bigger picture, or because you
get it all right.
