Clades can be objectively defined; traditional taxa cannot

Both, clades and traditional taxa (TT) can be objetively defined.

Say, a TT could be defined in terms of it content - list based taxon.
It is objective. A TT could be defined in terms of characters -
character based taxon. And so on. It could end up to be paraphyletic
or polyphyletic, but its definition will remain objective (otherwise
nothing without evolutionary history - planets, atoms, cars, climate,
etc - could be objetively defined).
