I say this with respect: your response looks as though you did not fully consider the impact of ring species as I had mentioned.

Please take a closer look and get back to me.

You can just say they have as much of a middle school definition of species as the racists, it's true even if it's rude

I was hoping if I was polite he would explain more of his insane "one animal, two species" point of view. Alas, I think he bumped his head on the logical contradiction and left.

In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two end populations in the series which are too distantly related to interbreed, though there is a potential gene flow between linked neighbouring populations.[1]

End points have differentiated enough to speciate, what's in between is a "sub-species" of both.

I don't understand how you think that's different then the normal process, it's literally the normal process when there isn't a clear geographical divide...

Your position is that something can be two species at once? I suppose that is one way to solve the problem of where to draw the line for speciation!

Completely out of line with the perspective of modern biology but fascinating and internally coherent none the less! It will take me years to fully digest this perspective. Thank you.

Saying that something can be two species at once is none the less not a compelling argument against the concept of a species being a social construct, as your perspective clashes with others'.
