I disagree. Homology is real. It is biological structure or form
which is passed from generation to generation amongst organisms
throught the information transmission processes of genetics and
epigenetics.

          Homology is a *generalization* about the *correspondence* of
          biological structures - - -

          It is *not* those structures themselves.

          Synapomorphy refers to those homology hypotheses

Do you extend this perspective to deny the reality of taxa? Is the
recognition and naming of Aves (with a proper name, no less) a
reification of mere ideas?

                   This seeming contradiction is resolved by
          understanding that taxa are not the sum of their
          synapomorphies, they are individuals connected by lineal
          descent.
