Your statement makes no sense. Anyone can draw a line between a chicken and a velociraptor. Anyone who argues that no line can be drawn between two etxremes are either deluded, insane, or with an agenda.
For purposes of scientific classification, the lines may blur sometimes. But the evidence at hand and discussions among experts does not seem to justify 3 different species. If so, one can only presume that those who wish there to be 3 species are finding ways to inflate/publish a paper and to claim a scientific stake, rather than there being some genuine need for classification.
