So you were pointing out the logical fallaciousness of your counter-argument?
I was contesting your definition of unicorn as being purely physical. Unicorns have magical properties, one of which is that they can only be seen by "true believers".
I was not creating a "counter-argument" to your definition of unicorns. I was merely appending your definition. If you really want to talk about unicorns please just let me know.
The entire subject of unicorns was brought up purely as an example of something that is unfalsifiable.
The falsifiable principle is a foundational concept of the scientific method.
You can't logically contend that something is simultaneously unfalsifiable AND real.
You can say, "it might be real", but that same argument also applies just as well to unicorns.
If your personal epistemological standards can't distinguish between what is real and what is merely unfalsifiable, then you MUST believe in unicorns.
