I stated what's incoherent about it. Your "Do you not think" is a non sequitur ... coherence is about meaning, and no one can say what the phrase means.
Aside from that, breathing fresh air in the morning is an activity, not a "quality of subjective experience". Generally the language people use around this is extremely confused and unhelpful.
I'm sure you think you're well intended, but your attempts at rigor have me scratching my head a little bit. I don't understand the defensiveness given that you haven't done the bare minimum to explain your position.
And no, that's not what a non sequitur is. And no, coherence is not just a linguistic idea. Then you try to explain what I "really mean" by "quality of subjective experience," and you can't even give a good faith reading of that. I'm really trying here.
