The side you are on has already won. Sequence data are universally accepted in systematics as the ultimate arbiters of evolutionary relationships, just delve into the modern classification of any extant group. One example of where molecular evidence overturned physical evidence long thought to be unambiguous, leading to a complete and essentially uncontested taxonomic overhaul: coprinoid mushrooms. Morphological characters are still used in paleontology for obvious reasons, but again within a higher-level framework provided by molecular phylogenetics.
