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.
